tx_flow_control_pause NIC => WRT54G

[Jorge Luis Gonzalez]

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,
