nit: I think this would be better expressed in a way that
rx_checksum_offload is assigned a boolean value (completely untested).

bool rx_checksum_offload = !!(priv->netdev->features & NETIF_F_RXCSUM);
Okay, I'll modify it in v2.
Maybe you can remove " in this module" from the patch title as it is
implicit. This comment/suggestion applies to all patches in this
series.

Sorry this may not have any bad effect,
so I don't plan to change it in V2.
If anyone else thinks it should be modified,
I will modify it.

Thanks a lot
Jijie Shao
