[OpenWrt-Devel] ath10k-ct issues - IBSS mode

Tue Mar 26 06:09:40 EDT 2019

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
