Subject: mt76: mt76x0: disable GTK offloading
|
||
|
|
|
||
|
|
When the GTK is offloaded, MT7610 won't transmit any multicast frames.
|
||
|
|
This is most likely due to a bug in the offloading datapath. MT7612 is
|
||
|
|
not affected.
|
||
|
|
|
||
|
|
Disable GTK offloading for now. It can be re-enabled once the bug in the
|
||
|
|
offloading path is fixed.
