    mac80211: remove direct probe step before authentication · 46cad4b7
    Johannes Berg authored
    The direct probe step before authentication was done mostly for
    two reasons:
     1) the BSS data could be stale
     2) the beacon might not have included all IEs
    The concern (1) doesn't really seem to be relevant any more as
    we time out BSS information after about 30 seconds, and in fact
    the original patch only did the direct probe if the data was
    older than the BSS timeout to begin with. This condition got
    (likely inadvertedly) removed later though.
    Analysing this in more detail shows that since we mostly use
    data from the association response, the only real reason for
    needing the probe response was that the code validates the WMM
    parameters, and those are optional in beacons. As the previous
    patches removed that behaviour, we can now remove the direct
    probe step entirely.
