The cert testing seems to encounter some wireless issues and is kept in-progress for that reason.

    mwifiex: Prevent memory corruption handling keys

    BugLink: https://bugs.launchpad.net/bugs/1892822

    [ Upstream commit e18696786548244914f36ec3c46ac99c53df99c3 ]

    The length of the key comes from the network and it's a 16 bit number. It
    needs to be capped to prevent a buffer overflow.

    Fixes: 5e6e3a92b9a4 ("wireless: mwifiex: initial commit for Marvell mwifiex driver")

From what I understand the expectations are to receive a 16bit number. However the AP used in testing allow/use 32bit. Which gets clipped by the fixed kernel driver and then the association to the AP fails.
