I actually thought about that while trying to implement this, but AFAIU (correct if wrong), gve_is_gqi and gve_is_qpl need priv to be initialized, so this feature set must be performed after gve_init_priv in this function. I suppose this feature checking maybe can be put before register_netdev. Do you prefer that? -- Thanks, Mina
