Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
|
||
|
|
|
||
|
|
Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
|
||
|
|
the RX and TX path. These filtered channel can in theory still be used by
|
||
|
|
the hardware but the signal strength is reduced so much that it makes no
|
||
|
|
sense.
|
||
|
|
|
||
|
|
There is already a DT property to limit the available channels but ath10k
|
||
|
|
has to manually call this functionality to limit the currrently set wiphy
|
||
|
|
channels further.
