      ath6kl: Fix target minimum length requirement for WMI_SEND_PROBE_RESPONSE_CMDID · bd24a50f
      Aarthi Thiruvengadam authored
      The firmware expects the minimum length of
      WMI_SEND_PROBE_RESPONSE_CMDID to be 13. However, when the device is a
      P2P GO and it needs to send a probe response to a non-P2P client,
      there are no P2P IEs to be added, and therefore the length of the WMI
      command is 12. This command gets rejected by the firmware. To fix
      this, add an extra byte to satisfy the minimum length requirement.

      ath6kl: Fix cfg80211 warning while starting IBSS mode · 4eab6f4f
      Raja Mani authored
      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).

      ath6kl: Fix packet drop when ath6kl_cookie runs out · 901db39c
      Vasanthakumar Thiagarajan authored
      "ath6kl: Maintain virtual interface in a list" mistakenly stops the
      netq only when the mode is ibss. This causes packet drops in sta mode
      when the available cookies (buffer abstraction in ath6kl and also used
      for tx throttling) runs out for the highest priority traffic. This patch
      just fixes this regression though the original code may still need fixes
      which can be addressed in separate patches.

      ath6kl: Fix accessing wrong skb->data in ath6kl_tx_complete() · f3803eb2
      Vasanthakumar Thiagarajan authored
      When buffer alignmnet is applied, the data pointer of skb taken from
      cookie will no longer point to the first byte of the actual data.
      But the skb->data pointer is used in ath6kl_tx_complete() to get
      the index of the virtual interface which will not give the correct
      interface index and sometimes may give the following WARN_ON() message.
      Use packet->buf instead of skb->data to fix this.
