0x11 on Solaris is DL_UNDELIVERABLE "Previous data unit could not be
delivered".  I've no idea whether it's the same on AIX; if it is, that's
some mysterious error somewhere in the bowels of the OS.

In any case, it's not an Ethereal or Tethereal error, it's a problem
with libpcap or with the OS code.

Try downloading and building libpcap 0.7 from tcpdump.org, which at
least tries to report DLPI errors in a less cryptic fashion.  Then
install that version of libpcap on top of the one you were using (you're
already using a version of libpcap other than the one that comes with
AIX, as the AIX one uses the weird mutant BPF that comes with AIX rather
than using DLPI, but the error message in question is from a libpcap
that uses DLPI), and then rebuild Ethereal and try again.
