Indeed. 

Peter, I suspect that driver is just buggy in some other way as opposed
to being re-entered; couldnt tell by inspection. It is possible it may
be too eager to open up before it really has space.
It will be easy to check your theory by having the driver just check if
it is netif_stopped just before it returns NETDEV_TX_BUSY.

jamal
