/**
* Parse subinterface names.
*
* The following subinterface syntax is supported. The first two are for
* backwards compatability:
*
* <intf-name> <id>
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with vlan id <id> and exact-match semantics.
*
* <intf-name> <min_id>-<max_id>
* - a set of the above subinterfaces, repeating for each id
* in the range <min_id> to <max_id>
*
* In the following, exact-match semantics (i.e. the number of vlan tags on the
* packet must match the number of tags in the configuration) are used only if
* the keyword exact-match is present. Non-exact match is the default.
*
* <intf-name> <id> dot1q <outer_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with vlan id <outer_id>.
*
* <intf-name> <id> dot1q any [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with any vlan id.
*
* <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
* <inner_id>.
*
* <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
*
* <intf-name> <id> dot1q any inner-dot1q any [exact-match]
*
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with any outer vlan id and any inner vlan id.
*
* For each of the above CLI, there is a duplicate that uses the keyword
* "dot1ad" in place of the first "dot1q". These interfaces use ethertype
* 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
* tagged packets the inner ethertype is always 0x8100. Also note that
* the dot1q and dot1ad naming spaces are independent, so it is legal to
* have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
*
* <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
* id <inner_id>.
*
* <intf-name> <id> untagged
* - a subinterface with the name <intf-name>.<id>. The subinterface
* has no vlan tags. Only one can be specified per interface.
*
* <intf-name> <id> default
* - a subinterface with the name <intf-name>.<id>. This is associated
* with a packet that did not match any other configured subinterface
* on this interface. Only one can be specified per interface.

* Create vlan subinterfaces
*
* @cliexpar
* @cliexstart{create sub-interfaces}
*
* To create a vlan subinterface 11 to process packets on 802.1q VLAN id 11, use:
*
* vpp# create sub GigabitEthernet2/0/0 11
*
* This shorthand is equivalent to:
* vpp# create sub GigabitEthernet2/0/0 11 dot1q 11 exact-match
*
* You can specify a subinterface number that is different from the vlan id:
* vpp# create sub GigabitEthernet2/0/0 11 dot1q 100
*
* You can create qinq and q-in-any interfaces:
* vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
* vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
*
* You can also create dot1ad interfaces:
* vpp# create sub GigabitEthernet2/0/0 11 dot1ad 11
* vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q 200
*
* Subinterfaces can be configured as either exact-match or non-exact match.
* Non-exact match is the CLI default. If exact-match is specified,
* packets must have the same number of vlan tags as the configuration.
* For non-exact-match, packets must at least that number of tags.
* L3 (routed) interfaces must be configured as exact-match.
* L2 interfaces are typically configured as non-exact-match.
*
* For example, a packet with outer vlan 100 and inner 200 would match this interface:
* vpp# create sub GigabitEthernet2/0/0 5 dot1q 100
*
* but would not match this interface:
* vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 exact-match
*
* There are two special subinterfaces that can be configured. Subinterface untagged has no vlan tags:
* vpp# create sub GigabitEthernet2/0/0 5 untagged
*
* The subinterface default matches any packet that does not match any other subinterface:
* vpp# create sub GigabitEthernet2/0/0 7 default
