Virtual networking refers to the ability of switches and routers to
configure logical topologies on top of the physical network
infrastructure, allowing any arbitrary collection of LAN segments
within a network to be combined into an autonomous user group,
appearing as a single LAN.

This package implement support (along with the kernel patch) :
+ Implements 802.1Q VLAN spec.
+ Can support up to 4094 VLANs per ethernet interface.
+ Scales well in critical paths: O(n), where n is the number of
 PHYSICAL ethernet interfaces, and that is only on ingress.
 O(1) in every other critical path, as far as I know.
+ Supports MULTICAST.
+ Can change MAC address of VLAN.
+ Multiple naming conventions supported, and adjustable at runtime.
+ 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, and is slightly faster.
