[dpdk-stable] [PATCH 1/3] net/sfc: move Rx checksum offload check to device level

[dpdk-stable] [PATCH 1/3] net/sfc: move Rx checksum offload check to device level

[Andrew Rybchenko]

Rx checksum offloads are on device level and should be checked and
enforced on device level.

Avoid logging of Rx checksum offloads enforced for each Rx queue.

[dpdk-stable] [PATCH 2/3] net/sfc: fix Rx queue offloads reporting in queue info

[Andrew Rybchenko]

CRC_STRIP offload is always enabled, but lost here.

It is more robust to use device level offloads directly to
compose returned value.
