Subject: [net 08/11] net/mlx5e: Remove HW-GRO from reported features

From: Gal Pressman <gal@...dia.com>

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.
