WEP and 802.11 drivers [fix committed]

[Sam Leffler]

Folks having trouble with WEP and the wi driver when operating in 
station mode should update and try again.  Beware that the default tx 
key is not set by default as previously so you need something like

ifconfig wi0 wepkey mumble weptxkey 2 wep

to configure WEP use.

WEP operation in ap mode probably needs some TLC and adhoc mode still 
needs the fix for the state machine bypassing the necessary setup of 
802.11 state.  Unless someone else steps up to fix these I'll get to 'em 
as time permits.
