    Subject[PATCH 08/55] staging: wfx: detect race condition in WEP authentication
    Date
    From: Jérôme Pouiller <jerome.pouiller@silabs.com>

    Current code has a special case to handle association with WEP. Before
    to rework the tx data handling, let's try to detect any possible misuse
    of this code.
