[ixp1200] ENP2505 Example Issues

[Cyrus Hall]

Thanks for the pointers.  Here is what I've tracked it down to.  When 
the octmac kernel modules is loaded (octmac.o) the packet spew begins. 
Inserting this module manually has the same result as running the ACE
load script.  I've tried recompiling the driver and made sure that it
was truly compiled for the ARM.  After a reboot the module seems in
insert, repeatably, just fine.  After one runs the ./ixstart script the
old behavior returns.  I tried running through the ./ixstart script by
hand several times and was unable to recreate the problem or start the
ACEs.

Has anyone run into this problem or similar ones in the past?  I'm going
to try using the kernel modules located in /lib/modules on the card next
and see if maybe the versions in /opt/ixasdk/bin/arm-be are bad.

Thanks for the comments,
