Hello! I recently install an Intel X710 based NIC into my unraid server (Specifically a AOC-STG-i4S X710-DA4) and the drivers included in kernel are from 2019. I checked several posts for others looking for drivers and was told to post here!
Link to the latest driver:

These NICs are becoming cheap and plentiful on the used market and can be easily flashed to allow any SFP making them attractive to homelab users.
