Subject: [PATCH iwl-net 0/3] Fix AF_XDP problems after changing queue number

Presented fixes address the following test-case:
* Run xdpsock on queue 10
* change number of combined channels to 20
* observe an error on xdpsock side

The first 2 patches deal with errors, the last one addresses the lack of
traffic.

Larysa Zaremba (3):
  ice: remove af_xdp_zc_qps bitmap
  ice: add flag to distinguish reset from .ndo_bpf in XDP rings config
  ice: map XDP queues to vectors in ice_vsi_map_rings_to_vectors()
