I would kind of expect that AFCP and ADCP are always encapsulated in
802.3/802.2 frames and never Ethernet, so rather than the Ethernet
TYPE field (16 bits) you have an SSAP/DSAP combination (two 8bit
values) in the 802.2 frame inside the raw 802.3 frame.  I think I
recall seeing $FC being used as the SAP value for AFCP, but I don't
know if ADCP is different.  The short answer is you might try $FCFC
and see what happens.  I don't have anything handy to verify all this,
so I could easily be wrong.  I'm sure Eero at HP, or someone who has
done what you are trying to do will be able to tell us for sure.
