====================
be2net: patch set
Hi David, as the below patch-set includes minor bug fixes and some
code re-org, pls consider applying it to the "net-next" tree. Thanks!
Patch 1 fixes a bit of code duplication involving interface object
creation code.
Patch 2 ensures that when a flow-control FW cmd fails, the adapter state
continues to reflect the old values. This allows for correct reporting
on subsequent ethtool "get".
Patch 3 returns proper error for link config change on BE3/Lancer
Patch 4 adds a kernel log message for FW boot error on Lancer
Patch 5 adds a function reset on Lancer as a part of the function init
sequence.
Patch 6 moves some FW-cmd definitions that belong in be_cmds.h, but
were placed in be_hw.h
Patch 7 resets the "bw_min" field while configuring "bw_max" needed
for TX rate limiting config.

net: stmmac: dwmac-rk: Fix phy regulator issues
This series fixes few issues in dwmac-rk:
1. Voltage settings was hardcoded into the driver for the phy regulator.
The driver now uses the default voltage settings found in the devicetree,
which are applied throught the regulator framework.
2. The regulator name used to power on or power off the phy was put in the devicetree
variable "phy_regulator", which is not standard and added a lot of code for nothing.
The driver now uses the devicetree property "phy-supply" and the corresponding functions
to manipulate this regulator.
The corresponding devicetree files are also updated. As this new binding for
rk3288 has not been released with any official kernel yet (not until 3.20),
I don't need to care about keeping compatibility with the old non standard property.

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

As these settings can be directly expressed from devicetree for both fixed
regulators and pmic-integrated regulators, it is more standard to set them
from dts and let the regulator framework use the right voltage informations
when it is used in the driver.

Always fully coalesce guest Rx packets into the minimum number of ring
slots. Reducing the number of slots per packet has significant
performance benefits when receiving off-host traffic.
Results from XenServer's performance benchmarks:
Baseline Full coalesce
Interhost VM receive 7.2 Gb/s 11 Gb/s
Interhost aggregate 24 Gb/s 24 Gb/s
Intrahost single stream 14 Gb/s 14 Gb/s
Intrahost aggregate 34 Gb/s 34 Gb/s
However, this can increase the number of grant ops per packet which
decreases performance of backend (dom0) to VM traffic (by ~10%)
/unless/ grant copy has been optimized for adjacent ops with the same
source or destination (see "grant-table: defer releasing pages
acquired in a grant copy"[1] expected in Xen 4.6).

Commit 5ac6f91d changed the igb driver to expose a zero (empty) mac
address to the VF on reset rather than a random one.
However, that behavioral change also requires igbvf driver changes
which can be hard especially when we want to talk to proprietary
guest OSs.
Looking at the code previous to the commit in Linux that made igbvf
work with empty mac addresses (8d56b6d), we can see that on reset
failure the driver will try to generate a new mac address with both
the old and the new code.
Furthermore, ixgbe does send reset failure when it detects an empty
mac address (35055928c).
So I think it's safe to make igb behave the same. With this patch I
can successfully run a Windows 8.1 guest with an empty mac address
and an assigned igbvf device that has no mac address set by the host.
If anyone is aware of a guest driver that chokes on NACK returns of
VF RESET commands, please speak up.

This patch cleans up the page reuse code getting it into a state where all
the workarounds needed are in place as well as cleaning up a few minor
oversights such as using __free_pages instead of put_page to drop a locally
allocated page.
It also cleans up how we clear the descriptor status bits. Previously they
were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

With the Intel 82527EI (driver: e1000e) there is an issue when running
the ptpd2 program, that leads to a kernel oops. The reason is here that
in e1000_xmit_frame() a work queue will be scheduled that has not been
initialized in this case. The work queue "tx_hwstamp_work" will only be
initialized if adapter->flags & FLAG_HAS_HW_TIMESTAMP set. This check
is missing in e1000_xmit_frame().
The following patch adds the missing check.

My previous patch to this file changed the code to be bug-compatible
towards userspace. Unless userspace (which I wasn't able to find)
implements the dump reader by hand in a wrong way, this isn't needed.
If it uses libnl or similar code putting multiple messages into a
single SKB is far more efficient.
Change the code to do this. While at it, also clean it up and don't
use so many variables - just store the address in the callback args
directly.

This tc action allows you to retrieve the connection tracking mark
This action has been used heavily by openwrt for a few years now.
There are known limitations currently:
doesn't work for initial packets, since we only query the ct table.
Fine given use case is for returning packets
no implicit defrag.
frags should be rare so fix later..
won't work for more complex tasks, e.g. lookup of other extensions
since we have no means to store results
we still have a 2nd lookup later on via normal conntrack path.
This shouldn't break anything though since skb->nfct isn't altered.

net: DSA fixes for bridge and ip-autoconf
These two patches address some real world use cases of the DSA master and slave
network devices.
You have already seen patch 1 previously and you rejected it since my
explanations were not good enough to provide a justification as to why it is
useful, hopefully this time my explanation is better.
Patch 2 solves a different, yet very real problem as well at the bridge layer
when using DSA network devices.
====================

DSA-enabled master network devices with a switch tagging protocol should
strip the protocol specific format before handing the frame over to
higher layer.
When adding such a DSA master network device as a bridge member, we go
through the following code path when receiving a frame:
__netif_receive_skb_core
-> first ptype check against ptype_all is not returning any
handler for this skb
-> check and invoke rx_handler:
-> deliver frame to the bridge layer: br_handle_frame
DSA registers a ptype handler with the fake ETH_XDSA ethertype, which is
called *after* the bridge-layer rx_handler has run. br_handle_frame()
tries to parse the frame it received from the DSA master network device,
and will not be able to match any of its conditions and jumps straight
at the end of the end of br_handle_frame() and returns
RX_HANDLER_CONSUMED there.
Since we returned RX_HANDLER_CONSUMED, __netif_receive_skb_core() stops
RX processing for this frame and returns NET_RX_SUCCESS, so we never get
a chance to call our switch tag packet processing logic and deliver
frames to the DSA slave network devices, and so we do not get any
functional bridge members at all.
Instead of cluttering the bridge receive path with DSA-specific checks,
and rely on assumptions about how __netif_receive_skb_core() is
processing frames, we simply deny adding the DSA master network device
(conduit interface) as a bridge member, leaving only the slave DSA
network devices to be bridge members, since those will work correctly in
all circumstances.
