Subject: [net-next 00/12][pull request] 40GbE Intel Wired LAN Driver Updates 2018-01-23

This series contains updates to i40e and i40evf only.

Pawel enables FlatNVM support on x722 devices by allowing nvmupdate tool
to configure the preservation flags in the AdminQ command.

Mitch fixes a potential divide by zero error when DCB is enabled and
the firmware fails to configure the VSI, so check for this state.
Fixed a bug where the driver could fail to adhere to ETS bandwidth
allocations if 8 traffic classes were configured on the switch.

Sudheer fixes a potential deadlock by avoiding to call
flush_schedule_work() in i40evf_remove(), since cancel_work_sync()
and cancel_delayed_work_sync() already cleans up necessary work items.
Fixed an issue with the problematic detection and recovery from
hung queues in the PF which was causing lost interrupts.  This is done
by triggering a software interrupt so that interrupts are forced on
and if we are already in napi_poll and an interrupt fires, napi_poll
will not be rescheduled and the interrupt is lost.

Avinash fixes an issue in the VF where is was possible to issue a
reset_task while the device is currently being removed.

Michal fixes an issue occurring while calling i40e_led_set() with
the blink parameter set to true, which was causing the activity LED
instead of the link LED to blink for port identification.

Shiraz changes the client interface to not call client close/open on
netdev down/up events, since this causes a lot of thrash that is
not needed.  Instead, disable the PE TCP-ENA flag during a netdev
down event and re-enable on a netdev up event, since this blocks all
TCP traffic to the RDMA protocol engine.

Alan fixes an issue which was causing a potential transmit hang by
ignoring the PF link up message if the VF state is not yet in the
RUNNING state.

Amritha fixes the channel VSI recreation during the reset flow to
reconfigure the transmit rings and the queue context associated with
the channel VSI.

The following are changes since commit c13da21cdb8085f1d9a53463c88a4d3967fe90fd:
  tun: avoid calling xdp_rxq_info_unreg() twice
