mac80211: fix wrong 160/80+80 MHz setting
Before this patch, STA's would set new width of 160/80+80 MHz based on AP capability only. This is wrong because STA may not support > 80MHz BW. Fix is to verify STA has 160/80+80 MHz capability before increasing its width to > 80MHz. The "support_80_80" and "support_160" setting is based on: "Table 9-272 — Setting of the Supported Channel Width Set subfield and Extended NSS BW Support subfield at a STA transmitting the VHT Capabilities Information field" From "Draft P802.11REVmd_D3.0.pdf" Signed-off-by: Aviad Brikman <aviad.brikman@celeno.com> Signed-off-by: Shay Bar <shay.bar@celeno.com> Link: https://lore.kernel.org/r/20200210130728.23674-1-shay.bar@celeno.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
