My NIC (Intel 100VE) is set to 100baseT/Full (autoneg off) running
into a Linksys WRT54G with the latest stock firmware. I'm getting
some high numbers in tx_flow_control_pause. Ideally, ethtool should
return a 0 for that line, I believe. Does anyone have any clues as to
why this might be happening? Outbound hops in traceroute don't show
any undue latency in the first hop, but the (outside) network is a bit
bursty. ifconfig shows no errors. The box is running FC6, stock
kernel.
On a related note, in Linux, should the MTU on the NIC be set to match
the MTU of the router (1492), or should I leave it at 1500?
Thanks for any help,
Jorge Luis
