System: NetBSD kaeru 3.99.7 NetBSD 3.99.7 (build.kaeru.nodebug) #74: Sat Jun 25 02:11:12 JST 2005 takashi@kaeru:/home/takashi/work/kernel/build.kaeru.nodebug i386

>Description:
	after updating kernel, wi(4) stops working for me.
	the same hardware used to work fine with a kernel around 20050614.
	i'm not using wep.

	all received packets will be dropped on "is_rx_unauth".
	to me, it seems that IEEE80211_NODE_AUTH is never set as
	wi_newstate doesn't call ieee80211_newstate.

	wi0 at pcmcia0 function 0: <ZyXEL, ZyAIR/100, >
	wi0: 802.11 address 00:a0:c5:15:14:05
	wi0: using RF:PRISM2 MAC:HFA3841 CARD:HWB3163 rev.A
	wi0: Intersil Firmware: Primary (0.3.0), Station (0.7.6)

>How-To-Repeat:
>Fix:
	the following patch works for me.
	i'm not sure if it's right, though.
