   4 Subject: [PATCH] brcmfmac: set txflow request id from 1 to pktids array size
   5
   6 Some PCIE firmwares drop txstatus if pktid is 0 and make packet held in
   7 host side and never be released. If that packet type is 802.1x, the
   8 pend_8021x_cnt value will be always greater than 0 and show "Timed out
   9 waiting for no pending 802.1x packets" error message when sending key to
  10 dongle every time.
  11
  12 To be compatible with all firmwares, host should set txflow request id
  13 from 1 instead of from 0.
