Merge branch 'xsk-tailroom-reservation-and-mtu-validation'
Maciej Fijalkowski says:
====================
xsk: tailroom reservation and MTU validation
here we fix a long-standing issue regarding multi-buffer scenario in ZC
mode - we have not been providing space at the end of the buffer where
multi-buffer XDP works on skb_shared_info. This has been brought to our
attention via [0].
Unaligned mode does not get any specific treatment, it is user's
responsibility to properly handle XSK addresses in queues.
With adjustments included here in this set against xskxceiver I have
been able to pass the full test suite on ice.
