471 * Parse subinterface names.
473 * The following subinterface syntax is supported. The first two are for
474 * backwards compatability:
477 * - a subinterface with the name <intf-name>.<id>. The subinterface
478 * is a single dot1q vlan with vlan id <id> and exact-match semantics.
480 * <intf-name> <min_id>-<max_id>
481 * - a set of the above subinterfaces, repeating for each id
482 * in the range <min_id> to <max_id>
484 * In the following, exact-match semantics (i.e. the number of vlan tags on the
485 * packet must match the number of tags in the configuration) are used only if
486 * the keyword exact-match is present. Non-exact match is the default.
488 * <intf-name> <id> dot1q <outer_id> [exact-match]
489 * - a subinterface with the name <intf-name>.<id>. The subinterface
490 * is a single dot1q vlan with vlan id <outer_id>.
492 * <intf-name> <id> dot1q any [exact-match]
493 * - a subinterface with the name <intf-name>.<id>. The subinterface
494 * is a single dot1q vlan with any vlan id.
496 * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
497 * - a subinterface with the name <intf-name>.<id>. The subinterface
498 * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
501 * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
502 * - a subinterface with the name <intf-name>.<id>. The subinterface
503 * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
505 * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
507 * - a subinterface with the name <intf-name>.<id>. The subinterface
508 * is a double dot1q vlan with any outer vlan id and any inner vlan id.
510 * For each of the above CLI, there is a duplicate that uses the keyword
511 * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
512 * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
513 * tagged packets the inner ethertype is always 0x8100. Also note that
514 * the dot1q and dot1ad naming spaces are independent, so it is legal to
515 * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
517 * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
518 * - a subinterface with the name <intf-name>.<id>. The subinterface
519 * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
522 * <intf-name> <id> untagged
523 * - a subinterface with the name <intf-name>.<id>. The subinterface
524 * has no vlan tags. Only one can be specified per interface.
526 * <intf-name> <id> default
527 * - a subinterface with the name <intf-name>.<id>. This is associated
528 * with a packet that did not match any other configured subinterface
529 * on this interface. Only one can be specified per interface.

725 * You can create qinq and q-in-any interfaces:
726 * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
727 * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
729 * You can also create dot1ad interfaces:
730 * vpp# create sub GigabitEthernet2/0/0 11 dot1ad 11
731 * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q 200
733 * Subinterfaces can be configured as either exact-match or non-exact match.
734 * Non-exact match is the CLI default. If exact-match is specified,
735 * packets must have the same number of vlan tags as the configuration.
736 * For non-exact-match, packets must at least that number of tags.
737 * L3 (routed) interfaces must be configured as exact-match.
738 * L2 interfaces are typically configured as non-exact-match.
740 * For example, a packet with outer vlan 100 and inner 200 would match this interface:
741 * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100
743 * but would not match this interface:
744 * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 exact-match
746 * There are two special subinterfaces that can be configured. Subinterface untagged has no vlan tags:
747 * vpp# create sub GigabitEthernet2/0/0 5 untagged
749 * The subinterface default matches any packet that does not match any other subinterface:
750 * vpp# create sub GigabitEthernet2/0/0 7 default
