====================
Intel Wired LAN Driver Fixes 2018-10-24

This series contains fixes for the ice driver.

Anirudh fixes a namespace issue which was introduced with a previous
patch to remove ice_netpoll.  Fixed up the device ID define names to
align with the branding string names.  Use the capability count returned
by the firmware, instead of calculating the count.  Introduced driver
workarounds due to current firmware limitations.  Fixed the queue
mapping for a VF, which needs to be set in the config and scatter queue
modes.  Fixed the driver which is setup to handle link status events
(LSE), even though the firmware does not have this feature yet, so add
the ability to poll for link status changes while we wait for updated
firmware.
