For sdio chip, it is high latency bus, all the TX packet's content will
be tranferred from HOST memory to firmware memory via sdio bus, then it
need much more memory in firmware than low latency bus chip, for low
latency chip, such as PCI-E, it only need to transfer the TX descriptor
via PCI-E bus to firmware memory. For sdio chip, reduce the complexity of
TX logic will help TX efficiency since its memory is limited, and it will
reduce the TX circle's time of each packet and then firmware will have more
memory for TX since TX complete also need memeory.
This patch disable TX complete indication from firmware for htt data
packet, it will not have TX complete indication from firmware to ath10k.
It will cut the cost of bus bandwidth of TX complete and make the TX
logic of firmware simpler, it results in significant performance
improvement on TX path.
Udp TX throughout is 130Mbps without this patch, and it arrives
400Mbps with this patch.
The downside of this patch is the command "iw wlan0 station dump" will
show 0 for "tx retries" and "tx failed" since all tx packet's status
is success.
This patch only effect sdio chip, it will not effect PCI, SNOC etc.
Tested with QCA6174 SDIO with firmware

To: ath10k; +Cc: linux-wireless
The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.
Test result of different length of data:
data packet(byte) cost time(us) calculated rate(Mbps)
256 28 73
512 33 124
1024 35 234
1792 45 318
14336 168 682
28672 333 688
57344 660 695
This patch change the TX packet from single packet to a large length
bundle packet, max size is 32, it results in significant performance
improvement on TX path.
This patch only effect sdio chip, it will not effect PCI, SNOC etc.
It only enable bundle for sdio chip.
Tested with QCA6174 SDIO with firmware
