Subject: [PATCH] brcmutil: really fix decoding channel info for 160 MHz
|
|
bandwidth

|
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")
