Sorry I'm late on a response.  I've been buried with work lately and 
haven't been paying much attention to mailing lists.

I confirmed your behavior on the 1900ACS using OpenWRT.  I opted for 
flent rrul_be and rrul tests rather than multiple netperfs though.

I'm happy to rejigger my build to be LEDE, rebuild, install, and run the 
test again.

Dunno about this one.

I certainly saw these behaviors as well but I've not run rrul against 
the WiFi in quite a while and I seem to remember a wireless firmware 
update happening since I last ran the test.

I'll re-run and see.
