In certain applications it's beneficial to allow the CPSW h/w
stats counters to continue to increment even while the kernel
polls them. This patch implements this behavior for both 1G
and 10G ethernet subsystem modules.

The CPSW driver keeps internally some, but not all, of
the statistics available in the hw statistics modules. Furthermore,
some of the locations in the hw statistics modules are reserved and
contain no useful information. Prior to this patch, the driver
allocates memory of the size of the the whole hw statistics modules,
instead of the size of statistics-entries-interested-in (i.e. et_stats),
for internal storage. This patch fixes that.

This patch fixes error in the setting of the hw statistics
module base for K2HK platform. In K2HK although there are
4 hw statistics modules, but only 2 are visible at a time.
Thus when setting up the pointers to the base of the
corresponding hw statistics modules, modules 0 and 2 should
point to one base, while modules 1 and 3 should point to the
other.

Commit 8d88c6ebb34c ("net: bcmgenet: enable MoCA link state change
detection") added a fixed PHY link_update callback for MoCA PHYs when
registered using platform_data exclusively, this change is also
applicable to systems using Device Tree as their primary configuration
interface.
In order for this to work, move the link_update assignment into
bcmgenet_moca_phy_setup() where we know for sure that we are running on
a MoCA GENET instance, and do not override phydev->link since this is:
- properly taken care of by the PHY library by getting the link UP/DOWN
interrupts
- this now runs everytime we call bcmgenet_open(), so we need to
preserve whatever we detected before we went administratively DOWN and
then UP
- we need to make sure that MoCA PHYs start with a link DOWN during
probe in order to force a link transition to occur
To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
above its caller.

Instead of multiplying the number of checks for IS_ERR(priv->clk),
simply NULLify the 'struct clk' pointer which is something the Linux
common clock framework perfectly deals with and does early return for
each and every single clk_* API functions.
Having every single function check for !IS_ERR(priv->clk) is both
redundant and error prone, as it turns out, we were doing it for the
main GENET clock: priv->clk, but not for the Wake-on-LAN or EEE clock,
so let's just be consistent here.

The current code returns from probe without waiting for the proper handling
of subchannels that may be requested. If the netvsc driver were to be rapidly
loaded/unloaded, we can trigger a panic as the unload will be tearing
down state that may not have been fully setup yet. We fix this issue by making
sure that we return from the probe call only after ensuring that the
sub-channel offers in flight are properly handled.

====================
tipc: clean up socket message reception
Despite recent improvements the message reception code in socket.c is
perceived as obscure and hard to follow, especially regarding the logics
for message rejection. With the commits in this series we try to remedy
this situation.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

When a message is received in a socket, one of the call chains
tipc_sk_rcv()->tipc_sk_enqueue()->filter_rcv()(->tipc_sk_proto_rcv())
or
tipc_sk_backlog_rcv()->filter_rcv()(->tipc_sk_proto_rcv())
are followed. At each of these levels we may encounter situations
where the message may need to be rejected, or a new message
produced for transfer back to the sender. Despite recent
improvements, the current code for doing this is perceived
as awkward and hard to follow.
Leveraging the two previous commits in this series, we now
introduce a more uniform handling of such situations. We
let each of the functions in the chain itself produce/reverse
the message to be returned to the sender, but also perform the
actual forwarding. This simplifies the necessary logics within
each function.

Currently, we use the code sequence
if (msg_reverse())
tipc_link_xmit_skb()
at numerous locations in socket.c. The preparation of arguments
for these calls, as well as the sequence itself, makes the code
unecessarily complex.
In this commit, we introduce a new function, tipc_sk_respond(),
that performs this call combination. We also replace some, but not
yet all, of these explicit call sequences with calls to the new
function. Notably, we let the function tipc_sk_proto_rcv() use
the new function to directly send out PROBE_REPLY messages,
instead of deferring this to the calling tipc_sk_rcv() function,
as we do now.

The shortest TIPC message header, for cluster local CONNECTED messages,
is 24 bytes long. With this format, the fields "dest_node" and
"orig_node" are optimized away, since they in reality are redundant
in this particular case.
However, the absence of these fields leads to code inconsistencies
that are difficult to handle in some cases, especially when we need
to reverse or reject messages at the socket layer.
In this commit, we concentrate the handling of the absent fields
to one place, by letting the function tipc_msg_reverse() reallocate
the buffer and expand the header to 32 bytes when necessary. This
means that the socket code now can assume that the two previously
absent fields are present in the header when a message needs to be
rejected. This opens up for some further simplifications of the
socket code.

Intel Wired LAN Driver Updates 2015-07-23
This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.
Emil extends the reporting of the RSS key and hash table by adding support
for x550 VFs.
Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
call to pm_qos_remove_request() to cleanup the QoS request made in
e1000_open().
Todd updates igb to report unsupported for ethtool coalesce settings
that are not supported. Also updated the driver to use the ARRAY_SIZE()
macro.
Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
which would never change dynamically. So update the switch() statement
to have a default case and switch on "new_latency_range" versus the
current ITR setting.
Shannon cleans up i40e code, where there were un-needed goto's. Also
clean up error status messages that were causing some confusion in
PHY and FCoE setup error reports.
Mitch updates the virtual channel interface to prepare for the x722 device
and other future devices, so that the VF driver can report what its
capable of supporting to the PF driver. Updates the i40evf driver to
handle resets like Core or EMP resets, where the device is reinitialized
and the VF will not get the same VSI.
Jesse updates the i40e and i40evf driver to use the kernel BIT() and
BIT_ULL() macros.

Use chan->state instead of chan->conn because waiting

Also avoids reference to the conn structure so makes

Only call __l2cap_wait_ack() when the needed condition
of chan->unacked_frames > 0 && chan->state == BT_CONNECTED
is true and convert the while loop to a do while loop.
__l2cap_wait_ack() change the function prototype to
pass in the chan variable as chan is already available
in the calling function l2cap_sock_shutdown(). Avoids

During execution of l2cap_sock_shutdown() which might
sleep, the sk and chan structures can be in an unlocked
condition which potentially allows the structures to be
freed by other running threads. Therefore, there is a
possibility of a malfunction or memory reuse after being
freed.
Keep the sk and chan structures alive during the
execution of l2cap_sock_shutdown() by using their
respective hold and put functions. This allows the structures
to be freeable at the end of l2cap_sock_shutdown().

This patch introduces suspend and resume callbacks to mac802154. When
doing suspend we calling the stop driver callback which should stop the
receiving of frames. A transceiver should go into low-power mode then.
Calling resume will call the start driver callback, which starts receiving
again and allow to transmit frames.
This was tested only with the fakelb driver and a qemu vm by doing the
following commands:
echo "devices" > /sys/power/pm_test
echo "freeze" > /sys/power/state
while doing some high traffic between two fakelb phys.
