Madwifi starting from rev3547 works slow

Description

Starting from [3548] the driver performs very slow (~100Kb) after some time. 100% way to force it into this "mode" is to force rate 54M, then auto with iwconfig. [3547] driver works OK - ~17Mb of actual throughout as measured by iperf.

Oh yes, I am using OpenSuse 11.1 with kernel from 11.0 (I am getting hangs with 11.1 kernel, tried to move to 11.0, but it does not seem to help).
