- * Implementation notes
- * FIXME:
- * - I don't support IPv6 addresses here, since SIOCGIFCONF can't return them
- *
- * There are three implemented methods for determining the MAC address of an
- * interface:
- * - a specific IOCTL (Linux)
- * - looking in the ARP cache (at least Solaris)
- * - using the sysctl interface (FreeBSD and Mac OS X)
- * Solaris and some others have SIOCGENADDR, but I haven't gotten that to work
- * on the Solaris boxes at SourceForge's compile farm, whereas SIOCGARP does.
