IBSS on wave-1, poor performance with encryption

[greearb]

Please see "Re: [OpenWrt-Devel] ath10k-ct 4.19 and IBSS" email thread on openwrt mailing list.

Performance is bad between two systems running wave-1 IBSS, but only with encryption enabled it seems.

Koen, please run with the attached firmware. It has debugging for the tx path you can enable. Please adjust these commands to match your particular debugfs path and phy name. Probably the first one is sufficient. The idea is to enable debugging, then start the connection and the most minimal amount of traffic that shows the problem. Then send me 'dmesg' output and I can decode it with a private tool and try to understand what is going on. firmware-2-htt-mgt-community.bin.gz

Enable verbose tx-path logs (if compiled in with -T option) (flags)

echo 0x9900000001 > /debug/ieee80211/wiphy0/ath10k/ct_special

Enable verbose rate-ctrl logs (if compiled in with -T option)

echo 0x9800000001 > /debug/ieee80211/wiphy0/ath10k/ct_special

And even more verbose (tx-pkt capture) (flags)

echo 0x9900000002 > /debug/ieee80211/wiphy0/ath10k/ct_special

RX path debugging (flags)
