wcn7850 - dmesg errors

[david Atkins]

Hi,

I'm seeing these messages in dmesg, not certain yet but suspect they coincide with the loss of connectivity on an active session.

We often see the connection disappear, ( traffic dies, no pings etc) then at some point it resumes.

Could this be related to the reporting that its a 3x3 when it's a 2x2?
