5b7f000ff9 ixgbe: add Tx anti spoofing support
This patch enables the ethertype Anti-Spoofing feature for affected
devices. It is configured such that LLDP packets sent by a VF will
be dropped.

9ac5c5ccdb ixgbevf: combine all of the tasks into a single service task
This change combines the reset and watchdog tasklets into a single task.

The advantage of this is that we can avoid multiple schedules of the reset
task when we have a reset event needed due to either the mailbox going down
or transmit packets being present on a link down.

e66c92ad58 ixgbevf: rewrite watchdog task to function similar to igbvf
This patch cleans up the logic dealing with link down/up by breaking down the
link detection and up/down events into separate functions - similar to how these
events are handled in other drivers.

e08400b707 ixgbevf: Add code to check for Tx hang
This patch adds code to allow for Tx hang checking.  The idea is to provide
more robust debug info in the event of a transmit unit hang. Similar to the
logic in ixgbe.

d9bdb57f9c ixgbevf: Fix ordering of shutdown to correctly disable Rx and Tx
This patch updates the ordering of the shutdown path so that we attempt to
shutdown the rings more gracefully. Basically the big changes are that we
shutdown the main Rx filter in the case of Rx and we set the carrier_off
state in the case of Tx so that packets stop being delivered from outside
the driver.  Then we shut down interrupts and NAPI.  Finally we stop the
rings from performing DMA and clean them.  This is a bit more graceful than
the previous path.

4dedadcbae ixgbe: Cleanup probe to remove redundant attempt to ID PHY
We always identify the PHY in our reset_hw path anyway so there is
no need to do it in get_invariants().  The reason I even noticed this
is that for new hardware (X550em) we don't assign some methods until
later in probe and calling phy.ops.read_reg could lead to a panic.

Conflicts:
	drivers/net/vxlan.c
	drivers/vhost/net.c
	include/linux/if_vlan.h
	net/core/dev.c

The net/core/dev.c conflict was the overlap of one commit marking an
existing function static whilst another was adding a new function.

In the include/linux/if_vlan.h case, the type used for a local
variable was changed in 'net', whereas the function got rewritten
to fix a stacked vlan bug in 'net-next'.

In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next'
overlapped with an endainness fix for VHOST 1.0 in 'net'.

In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter
in 'net-next' whereas in 'net' there was a bug fix to pass in the
correct network namespace pointer in calls to this function.

e8e7f018f1 net/mlx4_en: Adjust RX frag strides to frag sizes
This patch improves memory utilization and therefore the packets rate
for special MTU's. Instead of setting the frag_stride to the maximal
hard coded frag_size, use the actual frag_size that is set according to
the MTU, when setting the stride of the last frag.
So, for example, for MTU 1600, where the frag_size of the 2nd frag is
86, the frag_size is set to 128 instead of 4096. See below:

Before:
 frag:0 - size:1536 prefix:0 stride:1536
 frag:1 - size:86 prefix:1536 stride:4096

 frag 0 allocator: - size:32768 frags:21
 frag 1 allocator: - size:32768 frags:8

After:
 frag:0 - size:1536 prefix:0 stride:1536
 frag:1 - size:86 prefix:1536 stride:128

 frag 0 allocator: - size:32768 frags:21
 frag 1 allocator: - size:32768 frags:256

mlx4 IB driver under RoCE.

There are

1. Functions to go in/out to/from bonded mode
2. Function to remap virtual ports to physical ports

The bond_mutex prevents simultaneous access to data that keep status of
the device in bonded mode.

The upper mlx4 interface marks to the mlx4 core module that they
want to be subject for such bonding by setting the MLX4_INTFF_BONDING
flag. Interface which goes to/from bonded mode is re-created.

The mlx4 Ethernet driver does not set this flag when registering the
interface, the IB driver does.

627613f8f0 ath10k: prevent setting wrong key idx for station
Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.

The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.

Used TX_USAGE flag to set default key for stations.

Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

Registering the card as a wakeup source needs to

source needs to be changed too and this is done
via the set_wakeup() callback. Also, make sure
the device is removed properly using ath9k_deinit_wow().

fc8f0456dc mwifiex: disable UAPSD mode when AP starts
When AP is started, firmware exits power save mode. This
means power save manager of AP takes priority over station.
Firmware stop sending periodic AWAKE events to host.

We may have UAPSD enabled on station which buffers data
packets until AWAKE event from firmware. Data path is
unnecessarily blocked in this case. This patch disables
UAPSD mode to reenable transmit data path.
