4 Subject: [PATCH] brcmfmac: set txflow request id from 1 to pktids array size
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
12 To be compatible with all firmwares, host should set txflow request id
13 from 1 instead of from 0.
