====================
100GbE Intel Wired LAN Driver Updates 2019-09-03

This series contains updates to ice driver only.

Anirudh adds the ability for the driver to handle EMP resets correctly
by adding the logic to the existing ice_reset_subtask().

Jeb fixes up the logic to properly free up the resources for a switch
rule whether or not it was successful in the removal.

Brett fixes up the reporting of ITR values to let the user know odd ITR
values are not allowed.  Fixes the driver to only disable VLAN pruning
on VLAN deletion when the VLAN being deleted is the last VLAN on the VF
VSI.

Chinh updates the driver to determine the TSA value from the priority
value when in CEE mode.

Bruce aligns the driver with the hardware specification by ensuring that
a PF reset is done as part of the unload logic.  Also update the driver
unloading field, based on the latest hardware specification, which
allows us to remove an unnecessary endian conversion.  Moves #defines
based on their need in the code.

Jesse adds the current state of auto-negotiation in the link up message.
In addition, adds additional information to inform the user of an issue
with the topology/configuration of the link.

Usha updates the driver to allow the maximum TCs that the firmware
supports, rather than hard coding to a set value.

Dave updates the DCB initialization flow to handle the case of an actual
error during DCB init.  Updated the driver to report the current stats,
even when the netdev is down, which aligns with our other drivers.

Mitch fixes the VF reset code flows to ensure that it properly calls
ice_dis_vsi_txq() to notify the firmware that the VF is being reset.

Michal fixes the driver so the DCB is not enabled when the SW LLDP is
activated, which was causing a communication issue with other NICs.  The
problem lies in that DCB was being enabled without checking the number
of TCs.
