> 
> 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.
