    ath6kl: Fix cfg80211 warning while starting IBSS mode · 4eab6f4f
    Raja Mani 提交于
    When the connect event is received from the target in IBSS mode,
    cfg80211_ibss_joined() is called without informing BSS info to
    cfg80211 layer which internally hits the below WARN_ON message.

    This patch make sures that BSS info is delivered via cfg80211_inform_bss()
    to cfg80211 in advance before intimating IBSS status to cfg80211.
    
    In addition to this, one debug message is also added to know
    ad-hoc mode status (creator/joiner).
