498  * Parse subinterface names.
499  *
500  * The following subinterface syntax is supported. The first two are for
501  * backwards compatability:
502  *
503  * <intf-name> <id>
504  * - a subinterface with the name <intf-name>.<id>. The subinterface
505  * is a single dot1q vlan with vlan id <id> and exact-match semantics.
506  *
507  * <intf-name> <min_id>-<max_id>
508  * - a set of the above subinterfaces, repeating for each id
509  * in the range <min_id> to <max_id>
510  *
511  * In the following, exact-match semantics (i.e. the number of vlan tags on the
512  * packet must match the number of tags in the configuration) are used only if
513  * the keyword exact-match is present. Non-exact match is the default.
514  *
515  * <intf-name> <id> dot1q <outer_id> [exact-match]
516  * - a subinterface with the name <intf-name>.<id>. The subinterface
517  * is a single dot1q vlan with vlan id <outer_id>.
518  *
519  * <intf-name> <id> dot1q any [exact-match]
520  * - a subinterface with the name <intf-name>.<id>. The subinterface
521  * is a single dot1q vlan with any vlan id.
522  *
523  * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
524  * - a subinterface with the name <intf-name>.<id>. The subinterface
525  * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
526  * <inner_id>.
527  *
528  * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
529  * - a subinterface with the name <intf-name>.<id>. The subinterface
530  * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
531  *
532  * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
533  *
534  * - a subinterface with the name <intf-name>.<id>. The subinterface
535  * is a double dot1q vlan with any outer vlan id and any inner vlan id.
536  *
537  * For each of the above CLI, there is a duplicate that uses the keyword
538  * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
539  * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
540  * tagged packets the inner ethertype is always 0x8100. Also note that
541  * the dot1q and dot1ad naming spaces are independent, so it is legal to
542  * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
543  *
544  * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
545  * - a subinterface with the name <intf-name>.<id>. The subinterface
546  * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
547  * id <inner_id>.
548  *

744  *
745  * vpp# create sub GigabitEthernet2/0/0 11
746  *
747  * This shorthand is equivalent to:
748  * vpp# create sub GigabitEthernet2/0/0 11 dot1q 11 exact-match
749  *
750  * You can specify a subinterface number that is different from the vlan id:
751  * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100
752  *
753  * You can create qinq and q-in-any interfaces:
754  * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
755  * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
756  *
757  * You can also create dot1ad interfaces:
758  * vpp# create sub GigabitEthernet2/0/0 11 dot1ad 11
759  * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q 200
760  *
761  * Subinterfaces can be configured as either exact-match or non-exact match.
762  * Non-exact match is the CLI default. If exact-match is specified,
763  * packets must have the same number of vlan tags as the configuration.
764  * For non-exact-match, packets must at least that number of tags.
765  * L3 (routed) interfaces must be configured as exact-match.
766  * L2 interfaces are typically configured as non-exact-match.
767  *
768  * For example, a packet with outer vlan 100 and inner 200 would match this interface:
769  * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100
770  *
771  * but would not match this interface:
772  * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 exact-match
773  *
774  * There are two special subinterfaces that can be configured. Subinterface untagged has no vlan tags:
775  * vpp# create sub GigabitEthernet2/0/0 5 untagged
776  *
777  * The subinterface default matches any packet that does not match any other subinterface:
778  * vpp# create sub GigabitEthernet2/0/0 7 default
