In practice it means that VLAN interfaces behave 100% like
physical interfaces.

Specifically it makes SOCK_PACKET sockets on VLAN interfaces work.
dhcpd is the common application that uses them.

Optional header-reordering, to make the VLAN interface look JUST LIKE
an Ethernet interface. This fixes some problems with DHCPd and
anything else that uses a SOCK_PACKET socket. Default setting is off,
which works for every other protocol I know about, and is slightly
faster.
