commit 8edfc7a40e3300fc6c5fa7a3228a24d5bcd86ba5 upstream.
ice_port_vlan_on/off() was introduced in commit 2946204b3fa8 ("ice: implement bridge port vlan"). But ice_port_vlan_on() incorrectly assigns ena_rx_filtering to inner_vlan_ops in DVM mode. This causes an error when rx_filtering cannot be enabled in legacy mode.
Reproducer: echo 1 > /sys/class/net/$PF/device/sriov_numvfs ip link set $PF vf 0 spoofchk off trust on vlan 3 dmesg: ice 0000:41:00.0: failed to enable Rx VLAN filtering for VF 0 VSI 9 during VF rebuild, error -95
