> Subject: [PATCH v2] net/mlx4: fix CRC stripping capability report
> 
> There are two capabilities related to CRC stripping:
> 1. mlx4 HW capability to perform CRC stripping on a received packet.
> This capability is built in mlx4 HW. It should be returned by the API call
> mlx4_get_rx_queue_offloads().
> 2. mlx4 driver capability to enable/disable HW CRC stripping. This capability is
> dependent on the driver version.
> Before this commit the second capability was falsely returned by the
> mentioned API. This commit fixes it by returning the first capability.
> 
> mlx4 HW performs CRC stripping by default and this capability is always
> reported as "true".
> The ability to enable/disable CRC stripping is supported since this commit and
> requires OFED version 4.3-1.5.0.0 or rdma-core version v18.
> CRC stripping will be done by default regardless of its configuration when
> working with OFED or rdma-core versions earlier than those previously
> specified or before this commit.
