====================
Intel Wired LAN Driver Updates 2022-04-14

This series contains updates to ice driver only.

Maciej adjusts implementation in __ice_alloc_rx_bufs_zc() for when
ice_fill_rx_descs() does not return the entire buffer request and fixes a
return value for !CONFIG_NET_SWITCHDEV configuration which was preventing
VF creation.

Wojciech prevents eswitch transmit when VFs are being removed which was
causing NULL pointer dereference.

Jianglei Nie fixes a memory leak on error path of getting OROM data.
