Hi Amit,
I'm seeing quite a strange behavior of RedPine module.
It connects perfectly fine to one of access points but fails
to connect to another.
Moreover after that failure RSI driver starts to flood me with
messages saying:
--------------------->8--------------------
rsi_91x: rsi_sdio_check_buffer_status: Failed to read status register
--------------------->8--------------------
Below you may find details of my 2 experiments.
Note I use vanilla Linux kernel v4.14.4
Any ideas what could be wrong?

Could you enable driver debug zones and share dmesg log for analysis?

Hi Amitkumar,
Yet another observation with RS-9113 module.
I managed to setup an access point on my board with RS-9113 connected either
via SDIO (this one is soldered on my board) or via USB (this is your RS9113
Evaluation Board Rev 4.0).
But regardless the module I use I still see the same bandwidth figures.
RS-9113 sends data at ~100 Kbits and receives at ~1.5-2 Mbits.
See below results of iperf3 runs (from development host side).
The board with RS-9113 acts as a server:

I'm wondering if you may see different results in your setup and if so
could you please suggest something for me to try.
Thanks in advance,

P.S. I do remember about my previous email but so far I was not able to
get with the board to the place with "problematic" Wi-FI AP, once I get
there I'll grab longs for you.

Could you please specify which branch this patch is based on?
I tried to apply on 4.14.5 (whatever is latests in "linux-4.14.y")
but first 3 hunks failed to apply.
Maybe there're other dependencies?
Also a couple of questions about this patch.
Even though I'm not a networking/Wi-Fi expert of any kind but just
looking at your changes:
1. I assume for upstreaming that patch will be split in 5 seperate patches
each addressing its own item instead of doing all at once, right?
2. The only obvious change that might help me with bandwidth is increase
of a number of aggregated Tx frames. But bumping from 6 to 8 doesn't look
as a significant improvement. How that might bring Tx bandwidth at least to
what I see on Rx, i.e. make things 10 times faster?
Also while at it I'm wondering why 5GHz mode didn't work for me even though
"iw list" reports 5 GHz mode supported:
----------------------->8------------------
# iw list
Wiphy phy0
...
Frequencies:
* 5180 MHz [36] (20.0 dBm) (no IR)
# cat /etc/hostapd.conf

Has it something to do with your another fix in that patch?
