Re: [tipc-discussion] TIPC 2.0.0 packets not being transmitted

[Matthew C. <lin...@gm...>]

Hi, Erik,

As requested, pcap files.  The zc706 board is the problem child.

Also, I built a 3.14.2 (linux-xlnx tree) for the zedboard and it had no
problems with TIPC.  In fact, the pcap file for the zedboard is running the
3.14.2 kernel.  I'm build a 3.8.x and 3.10.x kernel for the zc706 to see if
that changes anything
