I'm not an expert on mac80211, but if you look at the code in drivers/net/wireless/rtl818x/rtl8187_dev.c, you will see that they TX packets are not queued by the driver. When the tx ops routine is called, the data is processed as required and the packet is sent on to the hardware. In the callback routine, certain status information is filled in and ieee80211_tx_status_irqsafe() is called to finish the transaction. You only need to worry about protecting the private data from concurrent access.
