When using the default sequence window size (100) I got the following in my logs: Jun 22 14:24:09 localhost kernel: [ 1492.114775] DCCP: Step 6 failed for DATA packet, (LSWL(6279674225) <= P.seqno(6279674749) <= S.SWH(6279674324)) and (P.ackno doesn't exist or LAWL(18798206530) <= P.ackno(1125899906842620) <= S.AWH(18798206548), sending SYNC... Jun 22 14:24:09 localhost kernel: [ 1492.115147] DCCP: Step 6 failed for DATA packet, (LSWL(6279674225) <= P.seqno(6279674750) <= S.SWH(6279674324)) and (P.ackno doesn't exist or LAWL(18798206530) <= P.ackno(1125899906842620) <= S.AWH(18798206549), sending SYNC... I went to alter the default sysctl and it didn't take for new sockets. Below patch fixes this. I think the default is too low but it is what the DCCP spec specifies. As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec to 3.5. This is still far too slow but it is a step in the right direction. Compile tested only for IPv6 but not particularly complex change.
