	This has nothing to do with the source code and everything to
do with the hardware.
	All 802.11b cards supported under Linux are :
		o 16 bits
		o PIO (no shared memory, no bus master)
		o use somewhat bloated host<->hw communication

	So, it's not like you have a choice...

	Host based WEP adds some overhead, if you don't like that get
yourself an up-to-date firmware so that you can offload WEP.
