========================================================================
Tx Path design algorithm:
Basically, we divide the packets into four types, Broadcast/Multicast, 11N Rate(AMPDU, AMSDU, Normal), B/G Rate(ARALINK, Normal),
Specific Packet Type. Following show the classification rule and policy for each kinds of packets.
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 :
(1).ARALINK
(2).Normal
