a57f98754e Fix enabling 40/80 MHz bandwidth support in the 6 GHz band
40/80 MHz bandwidth setting was being rejected due to incorrect sanity
check on the channel index. Fix that for the bandwidths larger than 20
MHz.

1e8ea0833d HE: Add HE support to hostapd_set_freq_params()
The parameters that need to be applied are symmetric to those of VHT,
however the validation code needs to be tweaked to check the HE
capabilities.

1011c79900 Do not enable HT/VHT for 6 GHz band 20 MHz width channels also
The previous commit had a rebasing issue that ended up covering only the
center_segment0 != 0 case. These were supposed to apply for all 6 GHz
band cases.

Move this implementation from check_40mhz_2g4() into a new helper

5f9b4afdfa Use frequency in HT/VHT validation steps done before starting AP
Using the channel parameter for validating allowed channel combinations
is not scalable to add 6 GHz support in the future since channel numbers
are duplicated between 2.4 GHz / 5 GHz bands and 6 GHz band. Hence use
frequency field for all channel combination validation steps done before
starting AP.

840532aea5 Search through all hw_features sets in hw_get_channel_freq()
The 5 GHz channels are stored in one hw_features set with mode
HOSTAPD_MODE_IEEE80211A while the 6 GHz channels will need to stored in
a separate hw_features set (but with same mode HOSTAPD_MODE_IEEE80211A)
due to possibility of different HE capabilities being available between
the 5 GHz and 6 GHz bands.

Search through all hw_features sets whose mode is same as the input mode
while finding channel corresponding to the input frequency in
hw_get_channel_freq().

ce6d9ce15b hostapd: Add supported channel bandwidth checking infrastructure
This adds checks to common code to verify supported bandwidth options
for each channel using nl80211-provided info. No support of additional
modes is added, just additional checks. Such checks are needed because
driver/hardware can declare more strict limitations than declared in the
IEEE 802.11 standard. Without this patch hostapd might select
unsupported channel and that will fail because Linux kernel does check
channel bandwidth limitations.

b0fc2ef3a3 hw_features: Fix check of supported 802.11ac channel width
The two channel width bits in the VHT capability field can be decoded in
following values (IEEE Std 802.11ac-2013 8.4.2.160.2 VHT Capabilities
Info field):

 * 0: no 160 or 80+80 MHz support
 * 1: 160 MHz support
 * 2: 160 and 80+80 MHz support
 * 3: (reserved)

The check must therefore not be done bitwise but instead it must checked
whether the capabilities announced by the driver are at least the ones
requested by the user.
