ah ok, I thought some 6LoWPAN ssh connection. :D > try ping6 with large packets but due to the problem in our receiver > I was only seeing every other packet of the fragmented PDU.

On sending side only a broadcast short address will be using if destination address is multicast. You can't use a long address here, see [3]. That's another problem of the current architecture. If you have an another stack != linux, then it's better to use long address only. > The version of Wireshark (1.10.2) I'm using shows the MAC header, it > even decodes the frame control field :) ah ok, sounds good. - Alex [1] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/net/ieee802154/6lowpan.c?id=refs/tags/v3.13#n211 [2] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/net/ieee802154/6lowpan.c?id=refs/tags/v3.13#n674 ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
