Sure. As for the real root cause, are you talking about the AP side? As
far as the station is concerened the initial packets are making it out
after a roam. So possibly the AP is restoring carrier before it should,
and packets are getting dropped.

In v2 I'll include a cover letter with more details about the test
setup, and what was observed.
