ath0 performence issues "ar9300_Stub_GetCTSTimeout" "ar9300_Stub_GetCTSTimeout

It seems re-aggregation for 11n is still broken, as I just faced the same
issue...

I had to connect to the 2.4 network since I have 5g set only to n.

truning on ath.0.hal.debug i see this:
getchannels: cc 0 regDmn 0x1ff mode 0xffffff ecm
getregstate: cc 0 rd 0x1ff
getchannels: !avail mode 0x1f800d (0x2) flags 0x2150
getchannels: too many channels for channel table
getchannels: cc 0 regDmn 0x1ff mode 0xffffff ecm
getregstate: cc 0 rd 0x1ff
getchannels: !avail mode 0x1f800d (0x2) flags 0x2150
getchannels: too many channels for channel table
wlan0: link state changed to UP
wlan0: link state changed to DOWN
getchannels: cc 0 regDmn 0x1ff mode 0xffffff ecm
getregstate: cc 0 rd 0x1ff
getchannels: !avail mode 0x1f800d (0x2) flags 0x2150
getchannels: too many channels for channel table

with dev.ath.0.debug I see a lot of this:
