This ensures that while a RX or TX status tasklet is scheduled only the according device interrupt is masked and other interrupts such as TBTT can still be processed. Also, this allows us to use tasklet_hi_schedule for TBTT and PRETBTT processing which is required to not send out beacons with a wrong DTIM count (due to delayed periodic beacon updates). Furthermore, this improves the latency between the TBTT and sending out buffered multi- and broadcast traffic. As a nice bonus, the interrupt handling overhead is reduced such that rt2800pci gains around 25% more throuhput on a rt3052 MIPS board.
