Since multicast frames are marked as no-ack, using IEEE80211_TX_STAT_ACK to check if they have been successfully transmitted by the driver is incorrect since a driver can choose to ignore transmission status for no-ack frames. This results in incorrect accounting for such frames. To fix this issue, this patch introduces a new flag that can be used by drivers to indicate error-free transmission of no-ack frames.
