nl80211: Disallow setting of HT for channel 14
This patch disables setting of HT20 and more for channel 14 because
the channel is only for IEEE 802.11b.
The patch for net/wireless/util.c was unit-tested.
The patch for net/wireless/chan.c was tested with iw command.
Before this patch.
$ sudo iw dev <ifname> set channel 14 HT20
$
After this patch.
$ sudo iw dev <ifname> set channel 14 HT20
kernel reports: invalid channel definition
command failed: Invalid argument (-22)
