Simple answer, don't wait in tx_timeout :)
These days drivers often need quite a while for hardware reset. I am
pushing to move this code, long term, into process context. So, in
tx_timeout:
* disable NIC and interrupts as best you can, quickly
* schedule_task/schedule_work to schedule the full hardware reset
