the curious thing is still that the fallback code applies only for 2.4

Hm, does RC fall back to 11na or 11a rates when doing 11ac? (in 5G
mode.) It's good to know fixing that would fix it in 2.4GHz operation
but yeah, I wonder about RC in 5G.
It appears the rate-ctrl tries to fall to CCK 2Mbps or 1Mbps and skips a/g
rates. /n
rates are a subset of VHT, so those are used as part of normal VHT rate-ctrl.
I have no explanation for why I saw the tx-hang in stock-ish firmware, which
indeed
should not have tried to use any a/g rates in 5Ghz. The high-level failure
looked exactly like
what I eventually debugged as falling back to /a rates in my firmware, for what
that
is worth.
Thanks,
Ben
