There was at least one bug that caused deadlocks with the version you used. If the current CVS version with the set_rid fix crashes the host computer, I would like to get some more information about this since I would like to fix these crashes before releasing the next driver version.

The driver passes all multicast/broadcast frames to the firmware and it is up to the firmware to decide when to really send these. However, unicast frames are buffered in the host driver if the station is using power saving.

Driver programmer's manual is available from Intersil, but it is distributed only under NDA.
