After a bisect, the first bad commit shows this:
commit 09a740ce352e1a1d16b9984115514ba9a4f4704b (refs/bisect/bad)

mac80211: receive and process S1G beacons
S1G beacons are 802.11 Extension Frames, so the fixed
header part differs from regular beacons.
Add a handler to process S1G beacons and abstract out the
fetching of BSSID and element start locations in the
beacon body handler.

From a glance through the diff, I'm at a loss as to why it causes the symptom. I manually
double-checked the bisect, an it appears correct.
What I see is that in the commit before this, I see a useful rx rate (1.3Gbps for instance)
in 'iw dev wlan1 station dump', but in this bad commit, both show 6Mbps rate. (Tx rate
in ath10k is probably broken for other reasons, so I only bisected the rx side issue.)
I'm using ath10k 9984 radio with firmware 10.4-3.9.0.2-00070 in station mode.
AP is an ath11k Hawkeye...
I'm using a 1Mbps UDP packet 'download' stream to make sure I'm seeing rates for data frames
and not just management frames.
Any idea what might be the issue?
Thanks,
Ben
