- fwohci_arrq_input: Do not return if next packet is in the buffer,
or the next packet cannot be received until the next receive interrupt.
- fwohci_uid_collect: XXX change M_WAITOK to M_NOWAIT for now, since there is
no lock but only one instance must be allowed here.
split fwohci_uid_req() and retry to get uid.
XXX need timer to wait some moment between retries...
- Add DELAY(10) for wait loop.
- split fwohci_buf_stop() into _stop_tx() and _stop_rx() because receiver
should not be stopped at bus-reset.
- split fwohci_buf_input() into _input() and _input_ppb() to improve
performance slightly.
