Sure. In that case i think we need to revert the other change that
checked the RX_TIMESTAMP flag as it corrected one issue but caused a
regression in Rx timestamp offload when it *is* functional.

I think its commit d21c2fe6e5a1 ("net/iavf: fix check for PF Rx
timestamp support"). That commit without this fix will incorrectly
prevent enabling Rx timestamps.

Thanks,
Jake
