Intel Wired LAN Driver Updates 2015-10-23

This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf.

Anjali adds a workaround to drop any flow control frames from being
transmitted from any VSI, so that a malicious VF cannot send flow control
or PFC packets out on the wire.  Also fixed a bug in debugfs by grabbing
the filter list lock before adding or deleting a filter.

Akeem fixes an issue where we were unconditionally returning VEB bridge
mode before allowing LB in the add VSI routine, resolve by checking if
the bridge is actually in VEB mode first.

Mitch fixed an issue where the incorrect structure was being used for
VLAN filter list, which meant the VLAN filter list did not get
processed correctly and VLAN filters would not be re-enabled after any
kind of reset.

Helin fixed a problem of possibly getting inconsistent flow control
status after a PF reset.  The issue was requested_mode was being set
with a default value during probe, but the hardware state could be a
different value from this mode.

Carolyn fixed a problem where the driver output of the OEM version
string varied from the other tools.

Jean Sacren fixes up kernel documentation by fixing function header
comments to match actual variables used in the functions.  Also
cleaned up variable initialization, when the variable would be
over-written immediately.

Hiroshi Shimanoto provides three patches to add "trusted" VF by adding
netlink directives and an NDO entry.  Then implement these new controls
in ixgbe and ixgbevf.  This series has gone through several iterations
to address all the suggested community changes and concerns.
