No, the "ixgbe" drivers is updated on "7/8/2021".

From Steve's response: 
     ME: "I guess this is just in C3000 reference board SDK ?"
     Steve: "It's the board covered by Intel Doc # 574437."

I check the doc "Last Updated: 11/07/2018".... It should be some kind of customer release, that's why
they are not in the official *open source* Linux driver, so keep your patch set as private.
