this adds support to ifconfig for reading info from transceivers.
it looks like this:
dlg@ix ifconfig$ sudo ./obj/ifconfig ix0 transceiver
ix0: identifier SFP (03)
connector: Copper Pigtail (21)
vendor: Amphenol
product: 616740001

Hi tech@,
When I had to change a HD between machines I figured out that -P option
of mount_mfs(8) does not work with DUIDs:
# mount_mfs -P ca7552589896b01e.d swap /mnt
mount_mfs: cannot stat ca7552589896b01e.d: No such file or directory
mount_mfs(8) already allows a DUID as the `special`
