Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 



Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2018-10-02

This series contains updates to ice driver only.

Anirudh expands the use of VSI handles across the rest of the driver,
which includes refactoring the code to correctly use VSI handles.  After
a reset, ensure that all configurations for a VSI get re-applied before
moving on to rebuilding the next VSI.

Dave fixed the driver to check the current link state after reset to
ensure that the correct link state of a port is reported.  Fixed an
issue where if the driver is unloaded when traffic is in progress,
errors are generated.

Preethi breaks up the IRQ tracker into a software and hardware IRQ
tracker, where the software IRQ tracker tracks only the PF's IRQ
requests and does not play any role in the VF initialization.  The
hardware IRQ tracker represents the device's interrupt space and will be
looked up to see if the device has run our of interrupts when a
interrupt has to be allocated in the device for either PF or VF.

Md Fahad adds support for enabling/disabling RSS via ethtool.

Brett aligns the ice_reset_req enum values to the values that the
hardware understands.  Also added initial support for dynamic interrupt
moderation in the ice driver.
