pktgen outputs for the various cases modified/unmodified[/others?]
would be nice, if you have a spot of time.

I am not familiar with pktgen but I seem to have it working for a simple
test.
I edited the 1-1 example from
ftp://robur.slu.se/pub/Linux/net-development/pktgen-testing/examples/ .
The results with and without the patch are below.
It looks like you ran pktgen on the embedded system, which exercised
only the transmit path. Auke indicated that the lockup was in the RU.
Have you run pktgen on a test system to fire packets at the embedded
system at max rate? Also test what happens when you fire packets in both
directions simultaneously.
