23 * L2 Emulation is a feautre that is applied to L2 ports to 'extract'
24 * IP packets from the L2 path and inject them into the L3 path (i.e.
25 * into the appropriate ip[4|6]_input node).
26 * L3 routes in the table_id for that interface should then be configured
27 * as DVR routes, therefore the forwarded packet has the L2 header
28 * preserved and togehter the L3 routed system behaves like an L2 bridge.
