Hi,

I'm trying to improve throughput of the Marvell 8686 sdio wlan module.
Unfortunately I have to stick with kernel 2.6.22.

Everything works except for very bad datarate. So far the mxc_mmc
driver does not handle any SDIO interrupts. Could that be the reason
for the bad performance? 


I figured, it does not make any difference wheter I use DMA for data
transfer or not (odd?)

I get only up to 90K/s.


thanks!

Andreas
