Extending HostAP to support WPA

[David Lu]

Hello,

I have checked the codes you mentioned. 

And I think you can write the codes like this:
char buf[26] = {0xdd, 0x18, ...}
local->func->set_rid(local->dev, HFA384X_RID_GENERICELEMENT,buf, 26);
                                                                 ~~~I think 26
should be (26+1)*2. I donot know about it exactly, pls just try it.^_^

You need not to tell firmware about the frame type of WPA, because RID FC48 is
just for WPA IE, firmware knew about it. I set IE in AP and sniffed frames,
it's good.

I am developing WPA support for AP now, and I met some questions in key
handshakes now. Hope you can talk about it with me.
