[Voyage-linux] Loss of AP function with Wistron DCMA-82 radio - v0.6

Hi Edwin,

Before the 0.6 release, I tested the following on madwifi AP functions:

1. simple 11b/g AP (ath0 and NAT to eth0 interfaces)
2. simple 11b/g AP bridge (ath0 and eth0 bridged)
3. AP + WPA encryption using hostapd.

There are some areas I did not test:
- dual radio
- adhoc/ahdemo
- wireless-tools WEP encryption

Hope this information help.

Regards,
Punky
