I've got lots of mlme splats, but this one appears to have useful info.
I'm instrumenting the rest before I post...
Test case it two VAPs, one under maximum load by two stations on another machine
sending/receiving UDP frames at max speed.
The local system also has 10 virtual stations, which are not doing much, but
they are quite often bouncing because they cannot get or keep a connection to
their AP on the peer machine (probably due to the excessive traffic on the
local AP). Getting lots of beacon-loss events on these stations.
I'll be happy to add more debugging if you have suggestions.
