Hi,
After days debugging, enabled CONFIG_MMC_DEBUG=y, I suspect the
mwifiex reset issue could still be a mwifiex bug.
I use firmware sd8801_uapsta.bin, it is able to connect to the WiFi
network, but reset either from WiFi modem or following command killed
WiFi, disabled mwifiex and wiped off /sys/kernel/debug/mwifiex/mlan0:

Looked at Douglas Anderson post "Fix Marvell WiFi reset by adding SDIO
API to replug card"
https://patchwork.kernel.org/project/linux-mmc/cover/[email protected]/,
I believe mwifiex should be able to replug card after reset, is it
still buggy or is it the firmware sd8801_uapsta.bin problem?
Thank you.
Kind regards,

I think I blocked most of this stuff out of my mind and it's also been
over 2 years. ;-) ...but any chance that Bluetooth could somehow be
involved, too? I seem to remember that things got complicated because
we could have both functions going at once. I think I advocated for
keeping it simple and always doing a full unplug / replug of the card
to reset it, but from notes I guess upstream landed it so you need to
handle the two cases (just WiFi vs WiFi+BT) in totally different ways.
It looks like there's ongoing discussion going on in
https://issuetracker.google.com/172214846. Maybe something there would
be helpful?

I think the main issue is many of you tested the mwifiex reset on
Marvell card (or BT?), unfortunately I am using uBlox Lily module
which is a WiFi only no Bluetooth, it is a iMX6ULL custom design, MMC
and SDIO are based on iMX6ULL EVK. I don't think anyone tested mwifiex
reset on that card, to make it worse, I am new to mwifiex, I might be
able to assist with debugging, but certainly not in the position to
contribute to fixing it.

I am using mwifiex on kernel upstream v4.19.75, does that include your
fix? Do you have a patch I can add to my Yocto build? Should I make
comments to the discussion at
https://issuetracker.google.com/172214846?
Thank you very much Doug.

Hi Doug,
I have updated the kernel to 5.10.59 which should be guaranteed to
include your reset patch.
But I could not connect to the WiFi.

Sorry, I think you're on your own here. I've only briefly touched upon
the Marvell reset code when I ran into trouble with it in the past but
it's definitely not something I have any real inside knowledge about.
My only suggestions would be to somehow get someone from Marvell (now
NXP I guess?) to help you debug or perhaps the people you got your
module from have some technical contacts that can help rope in someone
to help?
