>Description:
When I try and boot a system with the NDIS interface configured as:

ifconfig_ndis0="WPA DHCP"

I see it continuously trying to get a DHCP address, but it fails.  I found the problem is because wpa_supplicant is not realizing that it had successfully connected to the wireless network, so it continuously connects/disconnects.

By starting /usr/sbin/ndis_events, then wpa_supplicant will associate, and the wireless network is accessible.

hp010# dmesg | grep ndis
ndis0: <Broadcom 802.11b/g WLAN> mem 0xc0204000-0xc0205fff irq 21 at device 2.0 on pci6
ndis0: [ITHREAD]
ndis0: NDIS API version: 5.1
ndis0: using obsoleted if_watchdog interface
ndis0: Ethernet address: 00:14:a5:72:68:64
>How-To-Repeat:
set the NDIS interface to "WPA DHCP" and then reboot the system.
>Fix:
Start ndis_events before starting wpa_supplicant for NDIS interfaces.

apply the attached patch which will start ndis_events when the NDIS interface is set for WPA.
