Subject: [PATCH] wifi: cfg80211: report per wiphy radio antenna mask
|
|
|
|
With multi-radio devices, each radio typically gets a fixed set of antennas.
|
|
In order to be able to disable specific antennas for some radios, user space
|
|
needs to know which antenna mask bits are assigned to which radio.
