FYI, a libdlpi-based libpcap (PSARC/2008/288) was integrated into
snv_93, so the future is now. :-)

Indeed.  With Clearview UV, libnet would either have to be modified to
either use libdlpi, or minimally be modified to open DLPI devices out
of /dev/net in order to function with vanity naming.  That part, at
least, is architectural and needs to be addressed by this case.
