Stanislav Fomichev	5c399ae080	xsk: Add missing SPDX to AF_XDP TX metadata documentation ... Not sure how I missed that. I even acknowledged it explicitly in the changelog [0]. Add the tag for real now.

Stanislav Fomichev	11614723af	xsk: Add option to calculate TX checksum in SW ... For XDP_COPY mode, add a UMEM option XDP_UMEM_TX_SW_CSUM to call skb_checksum_help in transmit path. Might be useful to debugging issues with real hardware. I also use this mode in the selftests.
