You mean - by forcing some media. Autonegotiation should be on by default.
Duplex mismatch is a sure way to cripple the connection.

No idea about the first one; possibly just a way to throttle down number 
of messages by bundling them.

The second one was already discussed many times on this list. Search the

You'll have to decide whether the network traffic is most important for 
you and increase module parameter "max_interrupt_work" accordingly.
