      ath9: Fix ath_rx_flush_tid() for IRQs disabled kernel warning message. · 773b4e02
      Senthil Balasubramanian authored
      
      
      This patch addresses an issue with the locking order. ath_rx_flush_tid()
      uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211.
      
      As node clean up is still pending with ath9k and this problematic portion
      of the code is expected to change anyway, thinking of a proper fix may not
      be worthwhile. So having this interim fix helps the users to get rid of the
      kernel warning message.
      
      Pasted the kernel warning message for reference.

      ath9k: Incorrect key used when group and pairwise ciphers are different. · 1b96175b
      Senthil Balasubramanian authored
      
      
      Updating sc_keytype multiple times when groupwise and pairwise
      ciphers are different results in incorrect pairwise key type
      assumed for TX control and normal ping fails. This works fine
      for cases where both groupwise and pairwise ciphers are same.
      
      Also use mac80211 provided enums for key length calculation.
