In 40GE we can't use the default bw units for set ratelimit (100 Mbps)
since the max is 255*100 Mbps = 25 Gbps (not suited for 40GE), thus we need 1 Gbps units.
But for 10GE 1 Gbps units might be too bruit so we use the following solution.
For user set ratelimit <= 25 Gbps:
use 100 Mbps units * user_ratelimit (* 10).
For user set ratelimit > 25 Gbps:
use 1 Gbps units * user_ratelimit.
For user set unlimited ratelimit (0 Gbps):
use 1 Gbps units * MAX_RATELIMIT_DEFAULT (57)
Note: any value > 58 will damage the FW ratelimit computation, so we allow
a max and any higher value will be pulled down to 57.

====================
bridge: multicast snooping exports #2
Some people pointed out to me that it might be helpful to add stubs for
the newly added multicast exports. That way e.g. batman-adv should continue
to be compile and useable without having to have a kernel compiled
with bridge code in the future. This is what the first patch is supposed
to do.
The second patch adds a third multicast export for the bridge which
e.g. batman-adv is supposed to use, too, soon: Just like the bridge
disables its multicast snooping activities if no querier is present,
batman-adv needs to do the same if bridges are involved.
These three exports should be the final ones needed to marry the bridge
multicast snooping with the batman-adv multicast optimizations recently
added for the 3.15 kernel, allowing to use these optimzations in common
setups having a bridge on top of e.g. bat0, too. So far these bridged
setups would fall back to simple flooding through the batman-adv mesh
network for any multicast packet entering bat0.
More information about the batman-adv multicast optimizations currently
implemented can be found here:
http://www.open-mesh.org/projects/batman-adv/wiki/Basic-multicast-optimizations
The integration on the batman-adv side could afterwards look like this,
for instance (now including the third export):
http://git.open-mesh.org/batman-adv.git/commitdiff/61e4f6af4b7a21ed4040f2e711d50c778e5b6d93?hp=6ae4281474675fbca5bedcf768972a32db586eb6
====================
|
|
With this patch other modules are able to ask the bridge whether an
IGMP or MLD querier exists on the according, bridged link layer.
Multicast snooping can only be performed if a valid, selected querier
exists on a link.
Just like the bridge only enables its multicast snooping if a querier
exists, e.g. batman-adv too can only activate its multicast
snooping in bridged scenarios if a querier is present.
For instance this export avoids having to reimplement IGMP/MLD
querier message snooping and parsing in e.g. batman-adv, when
multicast optimizations for bridged scenarios are added in the
future.

====================
defxx: Fixes for 64-bit host support
This mini patch series addresses issues with 64-bit host support for FDDI
interface boards supported by the defxx driver where DMA mapping
synchronisation is required on swiotlb systems. While PDQ, the DMA engine
chip used with these boards, supports 48-bit addressing that would
normally suffice for typical 64-bit systems in existence, the host bus
interface chips used by individual implementations have their limitations
as follows:
* DEFTA or DEC FDDIcontroller/TURBOchannel -- there's no host bus
interface chip, the PDQ connects to TURBOchannel directly; TURBOchannel
supports DMA addressing of up to 16GB (34-bit addressing), however no
TURBOchannel system has ever been made that supports more than 1GB of
RAM, so in reality no remapping is ever required,
* DEFEA or DEC FDDIcontroller/EISA -- the ESIC EISA interface chip only
supports 32-bit addressing, all accesses beyond 4GB have to be remapped,
* DEFPA or DEC FDDIcontroller/PCI -- the PFI PCI interface chip rev. 1 & 2
only support 32-bit addressing, they have 32 AD lines only both on the
PDQ and the PCI side, and consequently no Dual Address Cycle support, so
all accesses beyond 4GB have to be remapped; the range of addressing
supported by PFI rev. 3 is currently not certain, however the chip is
backwards compatible with earlier revisions and will work with code that
supports them.
Some other issues discovered in the course of correcting 64-bit support
have been fixed as well. Each of the patches is functionally
self-contained and can be applied independentely, although there may be
mechanical dependencies making it necessary to apply patches in order.
The driver suffers from non-standard formatting and while I did my best
with these bug fixes to follow our coding style, I found some pieces
hopeless, checkpatch.pl will complain. I plan to reformat the whole
driver, that will inevitably require factoring out some pieces into
separate functions, but that's going to be a major effort and therefore I
want to do this separately, with no functional changes made at the same
time. If anyone has specific suggestions as to how to reformat any of the
pieces submitted here for a better layout, then I'll be happy to take them
into account.
And last but not least many thanks to Robert Coerver, who was the most
recent person to report this problem with the driver and was kind enough
to patiently try a few revisions of the driver update on his system as I
was finding and addressing issues.

This adds DMA synchronisation calls needed in the receive path:
1. To retrieve the Receive Status word that is prepended by the PDQ DMA
engine in the receive buffer, and provides information about the
frame received, including its size and any errors.
2. To make data received available for copying in the small-frame case
(size <= SKBUFF_RX_COPYBREAK) where the original DMA buffer will be
returned to the receive descriptor ring and therefore its mapping
retained.
With DMA mapping error handling in place, added by the other patch,
this may now also trigger where an attempt to map a newly allocated
buffer for DMA has failed. In that case data from the original buffer
will be copied out and the buffer returned to the DMA descriptor ring.
These calls may do nothing when data is in the host DMA addressing range
of the FDDI interface, such as always on 32-bit systems, however their
absence makes frame reception stop functioning reliably on systems that
have memory beyond the low 4GB of the address space.

This adds error handling for DMA mapping requests; I think there isn't
much else to say about it.
A good side-effect is the mapping in the transmit path is now made with
the board lock released. Also if DMA mapping fails for a newly
allocated receive buffer, then data from the old buffer will be copied
out (as is presently done for small frames only whose size does not
exceed SKBUFF_RX_COPYBREAK) and the original buffer returned, with its
mapping unchanged, to the DMA descriptor ring.

Prearranged receive DMA bounce buffer mappings are not released in the
card reboot/shutdown path. That does not affect frame reception, but
probably explains the random segmentation fault I observed the other day
on interface shutdown. Card is rebooted as required by the spec in the
process of ring fault recovery when a PC Trace signal has been received.
This change fixes the problem in an obvious manner.

Receive DMA maps are oversized, they include EISA legacy 128-byte
alignment padding in size calculation whereas this padding is never used
for data. Worse yet, if the skb's data area has been realigned indeed,
then data beyond the end of the buffer will be synchronised from the
receive DMA bounce buffer, possibly corrupting data structures residing
in memory beyond the actual end of this data buffer.
Therefore switch to using PI_RCV_DATA_K_SIZE_MAX rather than NEW_SKB_SIZE
in DMA mapping, the value the former macro expands to is written to the
receive ring DMA descriptor of the PDQ DMA chip and determines the
maximum amount of data PDQ will ever transfer to the corresponding data
buffer, including all headers and padding.

net: sctp: Optimisations to sctp command queue code
These 3 patches optimise the code that processes sctp's command queue.
(A list of 'tasks' to be performed after the rest of the chunk processing.)
1) Inline all the functions from command.c
2) Remove the memset() calls used to zero a word-sized union.
3) Use pointers instead of array indexes.
The combined changes reduce the code size (amd64) by a few kb.
I'm not 100% convinced that the zeroing done in patch 2 is needed at all.
On BE systems it is likely to generate more code than on LE ones.
In fact it might be best to change the union to only contain 'long' sized
items.
Changes for v2:
- Add some missing initialisers in patch 2/3 and delete them in 3/3.
- Modify the commit message for 2/3 to point out that the union
shouldn't need to be zeroed, but the patches aren't intended to
change the behaviour even if the code is buggy.

Even if memset() is inlined (as on x86) using it to zero the union
generates a memory word write of zero, followed by a write of the
smaller field, and then a read of the word.
As well as being a lot of instructions the sequence is unlikely to
be optimised by the store-load forward hardware so will be slow.
Instead allocate a field of the union that is the same size as the
entire union and write a zero value to it. The compiler will then
generate the required value in a register.
Zeroing the union shouldn't be necessary, but this patch series isn't
intended to have a behavioural change.

====================
net/hsr: Use list_head+rcu, better frame dispatch, etc.
This patch series is meant to improve the HSR code in several ways:
* Better code readability.
* In general, make the code structure more like the net/bridge code (HSR
operates similarly to a bridge, but uses the HSR-specific frame headers to
break up rings, instead of the STP protocol).
* Better handling of HSR ports' net_device features.
* Use list_head and the _rcu list traversing routines instead of array of slave
devices.
* Make it easy to support HSR Interlink devices (for future Redbox/Quadbox
support).
* Somewhat better throughput on non-HAVE_EFFICIENT_UNALIGNED_ACCESS archs, due
to lesser copying of skb data.
The code has been tested in a ring together with other HSR nodes running
unchanged code, on both avr32 and x86_64. There should only be one minor change
in behaviour from a user perspective:
* Anyone using the Netlink HSR_C_GET_NODE_LIST message to dump the internal
node database will notice that the database now also contains the self node.
All patches pass 'checkpatch.pl --ignore CAMELCASE --max-line-length=83
--strict' with only CHECKs, each of which have been deliberately left in place.
The final code passes sparse checks with no output.

This patch removes the separate paths for frames coming from the outside, and
frames sent from the HSR device, and instead makes all frames go through
hsr_forward_skb() in hsr_forward.c. This greatly improves code readability and
also opens up the possibility for future support of the HSR Interlink device
that is the basis for HSR RedBoxes and HSR QuadBoxes, as well as VLAN
compatibility.
Other improvements:
* A reduction in the number of times an skb is copied on machines without
HAVE_EFFICIENT_UNALIGNED_ACCESS, which improves throughput somewhat.
* Headers are now created using the standard eth_header(), and using the
standard hard_header_len.
* Each HSR slave now gets its own private skb, so slave-specific fields can be
correctly set.

set_advertising_complete function.

Having a single HCI_ADVERTISING flag is problematic since it tries to
track both the real advertising state and the corresponding mgmt
setting. To make the logic simpler and more reliable add a new flag that
only tracks the actual advertising state that has been written to the
controller.

====================
amd-xgbe: AMD 10Gb Ethernet driver updates
The following series fixes some bugs and provides new/changed support
in the driver.
- Fix a debugfs backward compatibility issue introduced by a previous patch
- Write to the interrupt enablement register, not the status register when
setting MTL interrupts
- Call netif_napi_del whenever the ndo_stop operation is called (to match
the call to netif_napi_add on ndo_open)
- Peformance enhancements:
- Adjusted default coalescing settings
- AXI DMA changes (burst length size and cache settings)
- ioread/iowrite reduction during interrupt
- Napi poll updates
- AXI DMA settings based on device tree property to account for a change in
the ARM64 default cache operations assignment
This patch series is based on net-next.

The default cache operations for ARM64 were changed during 3.15.
To use coherent operations a "dma-coherent" device tree property
is required. If that property is not present in the device tree
node then the non-coherent operations are assigned for the device.
Add support to the amd-xgbe driver to assign the AXI DMA cache settings
based on whether the "dma-coherent" property is present in the device
node. If present, use settings that work with the caches. If not
present, use settings that do not look at the caches.
