It's not minstrel_ht, it's this piece of code from net/mac80211/mlme.c:
if (enable_ht) {
hti_cfreq = ieee80211_channel_to_frequency(hti->control_chan,
sband->band);
/* check that channel matches the right operating channel */
if (local->hw.conf.channel->center_freq != hti_cfreq) {
/* Some APs mess this up, evidently.
* Netgear WNDR3700 sometimes reports 4 higher than
* the actual channel, for instance.
*/
printk(KERN_DEBUG
"%s: Wrong control channel in association"
" response: configured center-freq: %d"
" hti-cfreq: %d hti->control_chan: %d"
" band: %d. Disabling HT.\n",
sdata->name,
local->hw.conf.channel->center_freq,
hti_cfreq, hti->control_chan,
sband->band);
enable_ht = false;
}
}
