Therefore, VLAN pruning should be disabled if uplink is in switchdev mode. It is already being done in ice_eswitch_setup_env(), however the addition of ice_up() in commit 44ba608db509 ("ice: do switchdev slow-path Rx using PF VSI") caused VLAN pruning to be re-enabled after disabling it. Add a check to ice_set_vlan_filtering_features() to ensure VLAN filtering will not be enabled if uplink is in switchdev mode. Note that ice_is_eswitch_mode_switchdev() is being used instead of ice_is_switchdev_running(), as the latter would only return true after the whole switchdev setup completes.
