Subject: [PATCH] hostapd: update cfs0 and cfs1 for 160MHz
As per standard Draft P802.11ax_D8.0,( Table 26-9—Setting
of the VHT Channel Width and VHT NSS at an HE STA
transmitting the OM Control subfield ), center frequency of
160MHz should be published in HT information subset 2 of
HT information when EXT NSS BW field is enabled.
If the supported number of NSS in 160MHz is at least max NSS
support, then center_freq_seg0 indicates the center frequency of 80MHz and
center_freq_seg1 indicates the center frequency of 160MHz.
If the supported number of NSS in 160MHz is less than max NSS
support, then center_freq_seg0 indicates the center frequency of 80MHz and
center_freq_seg1 is 0. The center frequency of 160MHz is published in HT
operation information element instead.
