    cfg80211: Allow BSS hint to be provided for connect · 1df4a510

    This clarifies the expected driver behavior on the older
    NL80211_ATTR_MAC and NL80211_ATTR_WIPHY_FREQ attributes and adds a new
    set of similar attributes with _HINT postfix to enable use of a
    recommendation of the initial BSS to choose. This can be helpful for
    some drivers that can avoid an additional full scan on connection
    request if the information is provided to them (user space tools like
    wpa_supplicant already has that information available based on earlier
    In addition, this can be used to get more expected behavior for cases
    where a specific BSS should be picked first based on operations like
    Interworking network selection or WPS. These cases were already easily
    addressed with drivers that leave BSS selection to user space, but there
    was no convenient way to do this with drivers that take care of BSS
    selection internally without using the NL80211_ATTR_MAC which is not
    really desired since it is needed for other purposes to force the
    association to remain with the same BSS.
