- IPv6 support is incomplete
- Incoming UDP broadcast should only be accepted if listening on INADDR_ANY(?)
- Should add some driver call to support throttling... when there is no listener
for new data, the driver should be throttled.
for new data, the driver should be throttled. Perhaps the driver should disable
RX interrupts when throttled and re-anable on each poll time. recvfrom would,
of course, have to un-throttle.
o USB
- Implement USB device support

user stack allocation larger than needed.
o ARM/C5471
- Ethernet driver has problems on receive side. The cause of the problem seems
to be that the hardware waits for about 3 seconds before interrupting the driver.
By then, the sender has already retransmitted and things are out of sync.
Probable cause: TX configuration problem.
o ARM/DM320
- It seems that when a lot of debug statements are added, the system no
