- Subject: [PATCH] brcmutil: really fix decoding channel info for 160 MHz
- bandwidth
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Previous commit /adding/ support for 160 MHz chanspecs was incomplete.
- It didn't set bandwidth info and didn't extract control channel info. As
- the result it was also using uninitialized "sb" var.
- This change has been tested for two chanspecs found to be reported by
- some devices/firmwares:
- 1) 60/160 (0xee32)
- Before: chnum:50 control_ch_num:36
- After: chnum:50 control_ch_num:60
- 2) 120/160 (0xed72)
- Before: chnum:114 control_ch_num:100
- After: chnum:114 control_ch_num:120
- Fixes: 330994e8e8ec ("brcmfmac: fix for proper support of 160MHz bandwidth")
