I have a question about TCP packet retrans timeout.

(1) How to know TCP packet retrans timeout(how long)?
(2) How to change TCP packet retrans timeout?

Thanks in advance.

[I haven't followed the thread but new EMAC driver and 405EP rings
 a bell]

It's possible that the new method in which OCP code handles OCP device
dependencies has a bug.  405ep is a special case since it requires
a particular EMAC device to provide MDIO operations for both EMACs.
440gp/gx don't follow this code path.
