====================
100GbE Intel Wired LAN Driver Updates 2021-10-07

Michal Swiatkowski says:

The following patch series introduces basic switchdev model
support in ice driver. Implement the following blocks of
switchdev framework:
- VF port representors creation
- control plane VSI definition
- exception path (a. k. a. "slow-path") - to allow a virtual
switch or linux bridge to receive any packet that doesn't match
any hw filter
- link state management of virtual ports
- query virtual port statistics

Hardware offload support in switchdev mode is out of scope of
this patchset. Devlink interface is used to toggle between
switchdev and legacy (the default) modes of the driver.

---
Note: This series includes the use enum ice_status, however, we have
patches in our queue to remove it from the driver [1]. We are working
through the patches that precede the removal series.
