Re: [PATCH 2/2] mwifiex: don't clear cmd_sent flag in timeout handler

Hi James,

How did you know that by downgrading the firmware the problem has been
solved?. Did you see a scenario or flow in the driver that both
occurred when using the two different firmware but able to work on the
p80?.

The reason why I am asking is because sometimes the bug/s did not occur often.

Regards,

john
