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().

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. Signed-off-by: Dmitry Lebed <dlebed@quantenna.com>
