If there's any more info I can offer, please let me know...
>From the insmod of the new driver (I had unloaded an older driver earlier...and a de4x5
shortly after I added this one (as documented in an earlier email..))

This is after I start traffic, 25Mbps of UDP traffic on each of the 4 ports on the
ZNYX board... Btw, I'm loosing lots of UDP packets at this rate and the machine
(SBC, 550 Mhz pentium) is being over-worked. (~5% free cpu, according to top).
