6cf75f1ceb qed: Fix sending an invalid PFC error mask to MFW.
PFC error-mask value is not supported by MFW, but this bit could be
set in the pfc bit-map of the operational parameters if remote device
supports it. These operational parameters are used as basis for
populating the dcbx config parameters. User provided configs will be
applied on top of these parameters and then send them to MFW when
requested. Driver need to clear the error-mask bit before sending the
config parameters to MFW.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2017-04-18

This series contains updates to mainly ixgbe with only one ixgbevf change.

Usha adds a check to ensure the creation of number of VF's is valid based
on the traffic classes configured, all to avoid transmit hangs.

Joe Perches reduces the use of pr_cont since the output can be interleaved
by other processes.

Tony cleans up the code overwriting the KX4 config, which is configured by
the NVM.  Adds a check for MMNGC.MNG_VETO, to resolve an issue where we
were getting a link loss for the BMC when loading the driver.

Don fixes up SGMII x553 config details which were missed in earlier
implementations.  Added support for x552 XFI backplane interface support.
Cleaned up an unused define, which was causing confusion on supported
devices.

Emil fixes a link issue on KR parts by making sure the default setting is
set.  Refactors the code so that the code for allocating memory for the
list of MAC addresses that the VFs can use into its own function.  Made
some code cleans to help readability and ensure notification of SRIOV
being enabled is done upon completion.  Fixed an issue where if we failed
to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with
a NULL pointer dereference.

Philippe Reynes updates ixgbevf to use the new API for
{get|set}_link_ksettings.

Alex increases the headroom allocation when using build_skb() on a
system with 4K pages.  Fixed an issue in ixgbe_dump() where we were no
longer clearing the status bit.

9d386cd9a7 dp83640: don't recieve time stamps twice
This patch is prompted by a static checker warning about a potential
use after free.  The concern is that netif_rx_ni() can free "skb" and we
call it twice.

When I look at the commit that added this, it looks like some stray
lines were added accidentally.  It doesn't make sense to me that we
would recieve the same data two times.  I asked the author but never
recieved a response.

I can't test this code, but I'm pretty sure my patch is correct.

9d41accc1e mlxsw: spectrum: Add FID miss trap
When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.

This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

So far, mlxsw_sp_port_vlan_set range is limited by
MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is
wrapped up by a helper function which actually does multiple calls
to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set
and use it always. That allows caller not to care about the range.

8dc7d11f1d net/mlx4: suppress 'may be used uninitialized' warning
gcc 4.8.4 complains that mlx4_SW2HW_MPT_wrapper() uses an uninitialized
'mpt' variable:
  drivers/net/ethernet/mellanox/mlx4/resource_tracker.c: In function 'mlx4_SW2HW_MPT_wrapper':

     mpt->mtt = mtt;

I think this warning is a false complaint.  mpt is only used when
mr_res_start_move_to() return zero, and in all such cases it initializes
mpt.  But apparently gcc cannot see that.

Initialize mpt to avoid the warning.

0fcad45bdb rtlwifi: btcoex: 21a 2ant: add multiport action for p2p/miracast
For p2p/miracast, the wifi may have multiple ports for different roles.
Under this, we need extra settings for turning off the tdma and proper
coex table parameters.

We monnitor the number of links on a port to determine if it is for
p2p/miracast or not.

3506bc286a rtlwifi: btcoex: 21a 2ant: action for wifi is idle/linking/common
Depending on the state of wifi, we need to set different tdma and coex
table parameters to make wfi and bt coexist smoothly. Otherwise the
bt may have low sound quality or mouse lag, which mean bad user
experience. The same problem may occur on wifi also, if could disconnect
or lose some important packets.
