[ Upstream commit 761e0be2888a931465e0d7bbeecce797f9c311a3 ]
In switchdev mode the uplink VSI should receive all unmatched packets, including VLANs. 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.
