First one is a notification at the begining of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0), second one is a notification at the end of the dwell time with cmd_flag CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for the channel. Since there is a new state before the completion, the handler is to fixed so that the counts are deducted from the ones reported with CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE. Without this fix there will be lots of 0 msecs reported as active and busy time.
