Any ideas how I would go debugging this ? You could compile the driver with "DO_LOG" and see if anything interesting shows up in the system log. I don't see any obvious problem with private data vs. mbuf header (like in the Fore driver), but I still wonder if it is possible that this driver also needs to be updated. Is this problem associated with receiving data? Are you getting UDP checksum errors? ("netstat -p udp") Sorry, no good ideas pop to mind... -Richard > At 05:06 PM 1/18/2001 -0500, Mike Tancsa wrote: > > >I have been playing with the HARP stack and run into a small > >problem.
