Subjectmany "changed bandwidth, new config is" messages in the log
Hi,
I have only now managed to move to 4.9-rc5 (from 4.8) and started seeing
quite a lot of following messages
"
[ 346.612211] wlan0: AP c0:4a:00:f1:48:f2 changed bandwidth, new config is 2472 MHz, width 1 (2472/0 MHz)
[ 352.655929] wlan0: AP c0:4a:00:f1:48:f2 changed bandwidth, new config is 2472 MHz, width 2 (2462/0 MHz)
"

It always seems to be changing width from 1 -> 2 and back

$ dmesg | grep "changed bandwidth" | wc -l
42
in 13 minutes of uptime. I have noticed this came in via 30eb1dc2c430
("mac80211: properly track HT/VHT operation changes").

Is this something to be worried about?
