Staging: add rt2860 wireless driver

This is the Ralink RT2860 driver from the company that does horrible
things like reading a config file from /etc.  However, the driver that
is currently under development from the wireless development community
is not working at all yet, so distros and users are using this version
instead (quite common hardware on a lot of netbook machines).

So here is this driver, for now, until the wireless developers get a
"clean" version into the main tree, or until this version is cleaned up
sufficiently to move out of the staging tree.

Ported to the Linux build system and cleaned up a bit already by me.

+				Classification Rule=>
+					Multicast: (*addr1 & 0x01) == 0x01
+					Specific : bDHCPFrame, bARPFrame, bEAPOLFrame, etc.
+					11N Rate : If peer support HT
+								(1).AMPDU  -- If TXBA is negotiated.
+								(2).AMSDU  -- If AMSDU is capable for both peer and ourself.
+											*). AMSDU can embedded in a AMPDU, but now we didn't support it.
+								(3).Normal -- Other packets which send as 11n rate.
+
+					B/G Rate : If peer is b/g only.
+								(1).ARALINK-- If both of peer/us supprot Ralink proprietary Aggregation and the TxRate is large than RATE_6
+								(2).Normal -- Other packets which send as b/g rate.
+					Fragment:
+								The packet must be unicast, NOT A-RALINK, NOT A-MSDU, NOT 11n, then can consider about fragment.
+
+				Classified Packet Handle Rule=>
+					Multicast:
+								No ACK, 		//pTxBlk->bAckRequired = FALSE;
+								No WMM, 		//pTxBlk->bWMM = FALSE;
+								No piggyback,   //pTxBlk->bPiggyBack = FALSE;
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+					Specific :	Basically, for specific packet, we should handle it specifically, but now all specific packets are use
+									the same policy to handle it.
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+
+					11N Rate :
+								No piggyback,	//pTxBlk->bPiggyBack = FALSE;
+
+								(1).AMSDU
+									pTxBlk->bWMM = TRUE;
+								(2).AMPDU
+									pTxBlk->bWMM = TRUE;
+								(3).Normal
+
+					B/G Rate :
