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. --8<-- http://www.candelatech.com/~greear/vlan.html 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. -->8-- //Peter
