That's your problem.  Make it 10/half duplex.  Often auto-negotiation
doesn't work right, so force if 10/half duplex if you can.

The le0 interfaces don't support full duplex AFAIK.

Whenever you have a situation where you only get a small fraction of
the speed that your interface should be giving you, making sure that
everything is full duplex only if everything can support full duplex
should be your first step.
