Earlier qca9888 device was brought up using 10.1 firmware and then
later all firmware fixes and new features are migrated to 10.2/10.2.x

based firmware, removing 10.1 firmware support for qca9888 device.
Oh please do not do this. My 10.1 firmware works very nicely,
and out-performs 10.2 in my testing. Lots of people use my firmware
when they need IBSS support or other features not found in
official firmware, so it is not just me that will have
problems if you remove this support.
Aah.. I thought CT firmware is 10.2 based. Since most of firmware bug fixes and enhancements are integrated into 10.2 based firmware, we thought of get rid of
10.1 firmware to reduce code size. Moreover existing 10.1 official firmware has known issues. Is it possible to upgrade CT firmware to 10.2 WMI/HTT interfaces?
I have a 10.2 firmware too, but it is less stable, performs worse,
uses more RAM on the NIC (so I can do fewer virtual stations),
and I am not sure I can squeeze enough RAM out of it to port some
of the more interesting rate-ctrl fixes from 10.1 to 10.2.
I have recently started backporting a lot of 10.2.4 changes
into 10.1, which will aid any users on pre 4.0 kernels since they cannot
run 10.2.4 firmware w/out backporting.
I might could make my 10.1 work with a 10.2 driver API, but it would
take quite a bit of
effort, way more than what removing 10.1 from the driver saves in my opinion.
The driver already separates firmware specific logic pretty well, so I
don't think
it should be a huge maintenance effort to keep 10.1 support in the driver.
Maybe you could delete the 10.2 (not 10.2.4) firmware support and gain
some space that way? I
doubt anyone is using that productively....
Nope. There are customers who are still using 10.2.2 firmware. My kind advice is that please try to optimize latest firmware. 10.2 is nothing but based on 10.1
trunk so there wont be much interface difference... Will drop this series as of now...
10.2 has a significant re-work of the rate-ctrl. I think that is the main difference
that I see.
Maybe I can just copy the 10.1 rate-ctrl over 10.2 and get back the memory and performance
that I need. But, I have a bunch of other stuff to do first.
Thanks,
Ben
