The "Fail to stop Tx DMA" related issue plays a role. But not the major part. It accounts for about 3% of packet loss in my testbed. > CL>Is anyone looking at this issue?

With wireless-testing HEAD (671c924) I made the following observations with 3 nodes in a mesh using ch. 149 HT20 on AR9280. 1. ping -i0.1 does not cause aggregation to take place, and losses are 0% 2. a UDP iperf test with two nodes generating traffic shows losses around 1%. We can observe aggregation taking place in this case. Can either of you guys reproduce this with the latest wireless-testing? Also please CC devel@xxxxxxxxxxxxxxxxxxxx on any mesh bugs in the future.
