    cfg80211: validate scan channels · 584991dc
    Johannes Berg authored
    Currently it is possible to request a scan on only
    disabled channels, which could be problematic for
    some drivers. Reject such scans, and also ignore
    disabled channels that are given. This resuls in
    the scan begin/end event only including channels
    that are actually used.
    This makes the mac80211 check for disabled channels
    superfluous. At the same time, remove the no-IBSS
    check from mac80211 -- nothing says that we should
    not find any networks on channels that cannot be
    used for an IBSS, even when operating in IBSS mode.
