Hi,

So I figured out where the PHY transmission errors come from. That's
when the firmware tries to respond to a probe request, apparently the
driver/mac80211/hostapd don't handle probe response offloading and thus
the whole settings for probe responses are invalid, leading to phy
transmission errors. mac80211 or hostapd actually respond to the probe
responses then but it'd be nice if we could actually use the
offloading :)

We do upload a probe response template. But I think that there is a
bug in that code, too.
A TX error sounds like a bad PLCP or something. Maybe wrong packet size
given to the ucode. Did the SHM offset with the size actually change?
