Tx Path design algorithm:
526
Basically, we divide the packets into four types, Broadcast/Multicast, 11N Rate(AMPDU, AMSDU, Normal), B/G Rate(ARALINK, Normal),
527
Specific Packet Type. Following show the classification rule and policy for each kinds of packets.
528
Classification Rule=>
529
Multicast: (*addr1 & 0x01) == 0x01
530
Specific : bDHCPFrame, bARPFrame, bEAPOLFrame, etc.
531
11N Rate : If peer support HT
532
(1).AMPDU -- If TXBA is negotiated.
533
(2).AMSDU -- If AMSDU is capable for both peer and ourself.
534
*). AMSDU can embedded in a AMPDU, but now we didn't support it.
535
(3).Normal -- Other packets which send as 11n rate.
537
B/G Rate : If peer is b/g only.
538
(1).ARALINK-- If both of peer/us supprot Ralink proprietary Aggregation and the TxRate is large than RATE_6
539
(2).Normal -- Other packets which send as b/g rate.
541
The packet must be unicast, NOT A-RALINK, NOT A-MSDU, NOT 11n, then can consider about fragment.
543
Classified Packet Handle Rule=>
545
No ACK, //pTxBlk->bAckRequired = FALSE;
546
No WMM, //pTxBlk->bWMM = FALSE;
547
No piggyback, //pTxBlk->bPiggyBack = FALSE;
548
Force LowRate, //pTxBlk->bForceLowRate = TRUE;
549
Specific : Basically, for specific packet, we should handle it specifically, but now all specific packets are use
550
the same policy to handle it.
551
Force LowRate, //pTxBlk->bForceLowRate = TRUE;
554
No piggyback, //pTxBlk->bPiggyBack = FALSE;
