I took a little longer because I was not happy with the simple
cut'n'paste version. I believe the actual problem is that fcc_restart()
mustn't be called before netif_start_queue(). So the original version
only shortens the race period, it does not actually resolve it.
Unfortunately I'm deprived of suitable hardware as the focus of my work
has shifted in the last months, so I urge everyone out there to give it
