Ethernet start/stop

- Subject: [ECOS] Ethernet start/stop
What is the expected function of start and stop in an ethernet driver?
Some of the current drivers treat this as an enable/disable while others
do a complete reset, initialization, and possibly an auto-negotiation.
Since the driver start is called three times during normal
initialization this can lead to quite a delay during power-up (for
example the SMSC LAN91XXX driver can take up to 5 seconds per start as
currently written.)
Is there any particular driver that demonstrates the preferred mode of
operation for eCos?
Thanks,
Jeff
