Ok, I'll prioritise this (but I have not reviewed it yet).

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
The thread of read rx message by sdio bus from firmware is
synchronous, it will cost much time for process the left part
of rx message which includes indicate the rx packet to uppper
net stack. It will reduce the time of read from sdio.
This patch move the indication to a workqueue, it results in
From: Nicolas Boichat
When the FW bundles multiple packets, pkt->act_len may be incorrect
as it refers to the first packet only (however, the FW will only
bundle packets that fit into the same pkt->alloc_len).
Before this patch, the skb length would be set (incorrectly) to
pkt->act_len in
Tx complete message from firmware cost bus bandwidth of sdio, and bus
bandwidth is the bollteneck of throughput, it will effect the bandwidth
occupancy of data packet of TX and RX.
This patch disable TX complete indication from firmware for htt data
packet, it results in significant performance
The default credit size is 1792 bytes, but the IP mtu is 1500 bytes,
then it has about 290 bytes's waste for each data packet on sdio
transfer path for TX bundle, it will reduce the transmission utilization
ratio for data packet.
This patch enable the small credit size in firmware, firmware will
The max bundle size support by firmware is 32, change it from 8 to 32
will help performance. This results in significant performance
improvement on RX path.

The existing implementation of initiating multiple sdio transfers for
receive bundling is slowing down the receive speed. Combining the
transfers using a bundle method would be ideal.
The transmission utilization ratio for sdio bus for small packet is
slow, because the space
The bottleneck of throughout on sdio chip is the bus bandwidth, to the
patches are all to increase the use ratio of sdio bus.
