+ * if.c: (general) Handle upgrades from SUNWzebra, which tried
+ to track each logical interface as a seperate struct
+ interface, to Quagga, which assigns only one struct interface
+ per ifindex.
+ (if_sunwzebra_get) Try decompose a logical interface name
+ (fooX:Y) to the 'primary' name (fooX), for Solaris.
+ (interface_cmd) Use if_sunwzebra_get on Solaris.

+/* Need to handle upgrade from SUNWzebra to Quagga. SUNWzebra created
+ * a seperate struct interface for each logical interface, so config
+ * file may be full of 'interface fooX:Y'. Solaris however does not
+ * expose logical interfaces via PF_ROUTE, so trying to track logical
+ * interfaces can be fruitless, for that reason Quagga only tracks
+ * the primary IP interface.
+ *
+ * We try accomodate SUNWzebra by:
+ * - looking up the interface name, to see whether it exists, if so
+ * its useable
+ * - for protocol daemons, this could only because zebra told us of
+ * the interface
+ * - for zebra, only because it learnt from kernel
+ * - if not:
+ * - search the name to see if it contains a sub-ipif / logical interface
+ * seperator, the ':' char. If it does:
+ * - text up to that char must be the primary name - get that name.
+ * if not:
+ * - no idea, just get the name in its entirety.
