Subject: [PATCH] brcmfmac: fix reporting support for 160 MHz channels

Driver can report IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ so it's
|
||
|
|
important to provide valid & complete info about supported bands for
|
||
|
|
each channel. By default no support for 160 MHz should be assumed unless
|
||
|
|
firmware reports it for a given channel later.
|
||
|
|
|
||
|
|
This fixes info passed to the userspace. Without that change userspace
|
||
|
|
could try to use invalid channel and fail to start an interface.
