Hi,

this set is about fixing bpf_xdp_adjust_tail() usage in XDP progs for
multi-buffer AF_XDP. Both copy and zero-copy modes were broken.

Thanks,
Maciej

v2:
- fix !CONFIG_XDP_SOCKETS builds
- add reviewed-by tag to patch 3

Maciej Fijalkowski (3):
  xsk: recycle buffer in case Rx queue was full
  xsk: fix usage of multi-buffer BPF helpers for ZC XDP
  ice: work on pre-XDP prog frag count
