net/mlx5e: Remove HW-GRO from reported features
[ Upstream commit 6bbd723035badafe4a8eb17ccdecd96eae7a96d5 ]
We got reports of certain HW-GRO flows causing kernel call traces, which
might be related to firmware. To be on the safe side, disable the
feature for now and re-enable it once a driver/firmware fix is found.
