Because pcap_findalldevs() returns only interfaces that can be opened with
"pcap_open_live()", and loopback devices on Solaris are not DLPI
interfaces, and only DLPI interfaces support packet capture on Solaris.

By getting the source code to Solaris and modifying it so that you can
access the loopback device with DLPI (if that's even possible).

I.e., you're probably out of luck. If you need to capture on the loopback
device, you need to use Linux, Digital UNIX, or one of the BSDs (including
Mac OS X).
