Hi Ben,
Following our conversation from yesterday, here is a summary of all issues seen 
so far:

Test setup:

- Board: Mikrotik RB922
- Hardware used: on-board QCA9882 (QCA988x),  Wave1  2x2 .ac
- firmware's tested: both non-HTT and HTT flavours for qca988x

Synopsis:
- Setting the interface in IBSS mode results in following errors and spamming
- Speed is very low (100 kbit/s) upon linking 2 devices in HT20, long GI

Hello,

Do you see those SWBA overrun messages on both systems, or just one of them?

I'll work on fixing the out-of-my-tree compile for 4.20 today, as well as do
a quick test on 4.19 to see if I see that error below.

Thanks,
Ben

Hi Ben,

A huge amount of then continuously:

I updated ath10k-ct (commit-id: be5c21a82b15d28991500a28f7b2b6840356281f)

I fixed part of the issue with 4.20 not compiling in openwrt, but the other 
part appears to be
a backports issue, and I did not attempt to get that working.

Hi Ben,

This is still remaining using 4.20:

I think you will need to go back to 4.19 based driver, or add a hack to #ifdef 
that code out while compiling
in openwrt.

I did a brief test with the 4.19 ct driver and it seems to work OK in my test 
setup.  Since it appears openwrt
will be stuck on 4.19 for a while, I'll put some more effort into keeping my 
4.19 tree up to date.

Also, I found a nasty bug with mgt frames in htt-mgt mode yesterday, and 
uploaded new beta firmware to my
web page...will post csums and such to this list later today.

Thanks,
Ben
