netlink: specs: netdev: update doc for xsk tx-checksum and zc-max-segs

Browse source

Minor touch ups to the XSK-related doc strings in the netdev spec.

Tx checksum is (obviously?) Layer 4 (TCP/UDP), not Layer 3 (IP).

The xdp_zc_max_segs change is more subtle, I guess, but to kernel devs
saying "frags" may sound like the number of skb frags. The value includes
the head in this case. The default of 1 means single buffer, XDP_USE_SG
sockets are refused when it is 1. Let's use the word "buffer" instead
of "frag".
