H> VLAN_TRUNKDEV() requires epochification in ibcore after r353292.
Note that neither VLAN_DEVAT() not VLAN_TRUNKDEV() reference the
returned structure, so after epoch is exited the link is no longer
safe.
Does ibcore require these two functions in non-fast code paths?
Yes, ibcore use these in non-fast path.
Typically the ifnet's used will be referenced, and only the pointer
value is needed for deciding if a packet is designated for the given
network device or not.
