That tx-filter patch is already in my kernel. I believe this test was using ath9k
RC, so will try changing to minstrel_ht and see if that fixes anything.
My first concern is fixing the kernel crash related to removing
interfaces, so might be a day or two before I can get back to this
particular issue...
Thanks,
Ben
