ice: Fix VLAN pruning in switchdev mode

Browse source

[ Upstream commit 761e0be288 ]

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 44ba608db5 ("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.
