Hello,
I tried to figure out, if its possible to optimise the Datarate from the =
Host to NIC=20
finally to the Ethernet Bus .In the 3c59x.c (10Oct00)  its is mentioned =
that the ring_size_lenght is
important for effeciency.
But has annyone expierence with changing the  DnPriority/BurstTresh and =
TxStartThresh Registers.
Are they used annywhere in the driver ? And What about scheduled DPD for =
video streams .
I=B4m using the 905B (Cyclone)
