[net-next 0/9][pull request] 40GbE Intel Wired LAN Driver Updates 2017-05-31

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

This series contains updates to i40e and i40evf only.

Jesse provides a couple of fixes, starting with cleaning up duplicate
lines of code.  Fixed a missing line which enables RSS as a negotiated
feature.  Since the VF does not have any way of reporting FCoE enabled,
so just force the code to always report FCoE as disabled.

Jake provides several fixes and changes, starting with fixing a race
condition in i40e.  The hardware has a limitation on transmit PTP packets,
which requires us to limit the driver to timestamping a single packet at
once.  This is done using a state bitlock which enforces that only one
timestamp request is honored at a time, unfortunately this suffers from
a race condition.  Fixed a corner case where we failed to cleanup the
bit lock after a failed transmit, and resulted in a state bit being
locked forever.  Added a new statistic which tracks when a transmit
timestamp request is skipped/ignored, since the driver can only handle
one transmit timestamp request at a time.

Christophe Jaillet fixes a NULL pointer dereference if kzalloc fails.

The following are changes since commit ffe406457753a7ca2061ecc8c4d3971623066911:
  bnxt_en: Fix xmit_more with BQL.
