[ Upstream commit 15a5078cab30d7aa02ad14bfadebf247d95fc239 ]
When the driver is in switchdev mode and rx-gro-hw is set, the RQ needs special CQE handling. Till then, block setting of rx-gro-hw feature in switchdev mode, to avoid failure while setting the feature due to failure while opening the RQ.
