- There is a compiler optimization problem. At -O2, there is odd
behavior on pings and ARP messages. But the behavior is OK with
optimization disabled. This may or may not be a compiler issue; it
may be a timing issue.
- The driver does not work with I- and D-Caches enabled. The behavior
is just as for when compiler optimization is enabled. I have not
yet found in coherency issues so this migh also be timing related.
