[PATCH net-next 0/3][pull request] 1GbE Intel Wired LAN Driver Updates 2021-08-27

Aravindhan Gunasekaran says:

This adds support for Credit-based shaper qdisc offload from
Traffic Control system. It enables traffic prioritization and
bandwidth reservation via the Credit-Based Shaper which is
implemented in hardware by i225 controller.

Patch 1/3 adds a default cycle-time for TSN mode to be configured.

Patch 2/3 helps to separate TSN mode programming on the fly and
during reset sequence. It also simplifies handling features flags
for various TSN modes supported by i225 in the driver.

Patch 3/3 adds support for IEEE802.1Qav(CBS) standard
implemented in i225 HW. Two sets of CBS HW shapers are present
in i225 and driver enables them in the two high priority queues.

The following are changes since commit 4baf0e0b329874ec5e85480f53851b5f05a7ae58:
