It should, but only in very limited cases.
For example, it probably only works properly when HW vlan assist
is being used on TX. It's likely that the chips which don't support
VLAN assist also can't handle VLAN headers in their TX checksumming
engine.
Because it is very chip dependant whether this works or not in
any case, we should probably create a special features flag for
this. Something like NETIF_F_VLAN_INHERIT_FEATURES.
