So it is indeed - as expected of course - advertising that it's about to
switch channel and even saying everyone else needs to be *quiet*. This
is
struct ieee80211_ext_chansw_ie {
u8 mode;
u8 new_operating_class;
u8 new_ch_num;
u8 count;
} __packed;
so mode==1 indicates quiet, new_operating_class/new_ch_num are actually
the channel it's currently on, and count is 9.
Can you say if it actually changes the count? Maybe capture on channel
36 using the NIC as a sniffer what it does over time:

Initially I'd say though that if this situation persists, then your AP
is having some problems and we'd not have stayed connected without the
patch in question either. If you want, maybe revert and see what the
symptom is then?
