====================
100GbE Intel Wired LAN Driver Updates 2019-09-05

This series contains updates to ice driver.

Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.

Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array.  Adds a pointer
check to prevent a NULL pointer dereference.  Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable.  Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s.  Updates the printed strings to make it
easier to search the logs for driver capabilities.

Jesse cleans up unnecessary function arguments.  Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.

Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.

Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.

Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.

Ashish updates the transmit context structure based on recent changes to
the hardware specification.

Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.
