[dpdk-dev,v3] i40e: fix VLAN filter in promiscuous mode
Commit Message
For VLAN filtering VLAN table should be enabled.
But VLAN table is disabled by default until a rule added. In
promiscuous mode no rule is added to enable the VLAN table.
So this patch clears promiscuous VLAN flag on VSI, and adds a
rule to enable VLAN table to fix VLAN filtering in promiscuous
mode.
Fixes: 4861cde46116 ("i40e: new poll mode driver")
