Subject: mac80211: fix warning in 6 GHz IE addition in mesh mode
|
|
|
|
The commit 24a2042cb22f ("mac80211: add HE 6 GHz Band Capability
|
|
element") failed to check device capability before adding HE 6 GHz
|
|
capability element. Below warning is reported in 11ac device in mesh.
|
|
Fix that by checking device capability at HE 6 GHz cap IE addition
|
|
in mesh beacon and association request.
