[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Manish Rangankar <mrangankar@xxxxxxxxxxx>

User accidently pass module param ql2xenabledif=1, which is unsupported
in driver, but driver still progress and lead to guard tag error during
device discovery.

Remove unsupported ql2xenabledif=1 option and validate the user input.
