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

Jeff Kirsher says:

====================
This series contains updates to the ice driver only.

Bruce updates the driver to store the number of functions the device has
so that it won't have to compute it when setting safe mode capabilities.
Adds a check to adjust the reporting of capabilities for devices with
more than 4 ports, which differ for devices with less than 4 ports.

Brett adds a helper function to determine if the VF is allowed to do
VLAN operations based on the host's VF configuration.  Also adds a new
function that initializes VLAN stripping (enabled/disabled) for the VF
based on the device supported capabilities.  Adds a check if the vector
index is valid with the respect to the number of transmit and receive
queues configured when we set coalesce settings for DCB.  Adds a check
if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX
so that VLAN 0 promiscuous rules to be removed.  Add a helper macro for
a commonly used de-reference of a pointer to &pf->dev->pdev.

Jesse fixes an issue where if an invalid virtchnl request from the VF,
the driver would return uninitialized data to the VF from the PF stack,
so ensure the stack variable is initialized earlier.  Add helpers to the
virtchnl interface make the reporting of strings consistent and help
reduce stack space.  Implements VF statistics gathering via the kernel
ndo_get_vf_stats().

Akeem ensures we disable the state flag for each VF when its resources
are returned to the device.

Tony does additional cleanup in the driver to ensure the when we
allocate and free memory within the same function, we should not be
using devm_* variants; use regular alloc and free functions.

Henry implements code to query and set the number of channels on the
primary VSI for a PF via ethtool.

Jake cleans up needless NULL checks in ice_sched_cleanup_all().

Kevin updates the firmware API version to align with current NVM images.

v2: Added "Fixes:" tag to patch 5 commit description and added the use
    of netif_is_rxfh_configured() in patch 13 to see if RSS has been
    configured by the user, if so do not overwrite that configuration.
