Tony - thanks for the confirmation. I'm at IETF 86 this week and booked pretty solid. I expect to get back to my fragmentation code this weekend and will follow up with questions or patches. - Ralph On Mar 11, 2013, at 2:03 PM 3/11/13, Tony Cheneau wrote: > Hi, > > Sorry for the delay, I w

Thanks, Tony. I've cloned net-next and will start working against that version of 6lowpan.c, etc. I'll be happy to contribute any fixes I develop if I can figure out how to prepare and submit them. - Ralph On Feb 12, 2013, at 10:37 AM 2/12/13, Tony Cheneau wrote: > Hello Ralph, > > I want

I'm working on fragmentation in 6lowpan.c. I've fixed a problem with the offset computation. According to RFC 6282, the offset in the fragmentation head is supposed to give the lotion of the fragment data in the original (uncompressed) datagram. 6lowpan.c computes the offset from the compress

2013-02-11 Thread Ralph Droms
I'm trying to bring up the linux-zigbee stack and I'm running into problems with 6lowpan.c I'm concerned about tracking down and fixing these problems, because they seem pretty fundamental and, as far as i can tell, would prevent this stack from interoperating with other RFC-compliant stacks.
