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



Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2021-02-08

This series contains updates to the ice driver and documentation.

Brett adds a log message when a trusted VF goes in and out of promiscuous
for consistency with i40e driver.

Dave implements a new LLDP command that allows adding VSI destinations to
existing filters and adds support for netdev bonding events, current
support is software based.

Michal refactors code to move from VSI stored xsk_buff_pools to
netdev-provided ones.

Kiran implements the creation scheduler aggregator nodes and distributing
VSIs within the nodes.

Ben modifies rate limit calculations to use clock frequency from the
hardware instead of using a hardcoded one.

Jesse adds support for user to control writeback frequency.

Chinh refactors DCB variables out of the ice_port_info struct.

Bruce removes some unnecessary casting.

Mitch fixes an error message that was reported as if_up instead of if_down.

Tony adjusts fallback allocation for MSI-X to use all given vectors instead
of using only the minimum configuration and updates documentation for
the ice driver.
