I'm using ecos-3.0 + lpc2478. Now I have a problem. My eth can
only works well at 10 M . It losses a lot packages at 100 M .
FreeBSD stack .

The problem still ocurrs if setting system clock to 72M (which is 48M
before). If sending packets from equipment(ecos) to computer (by udp)
. All packets are successfully received. If sending from computer to
ecos . Some irq does not occur. Some irq occurs but packets not be
transferred to my application. About 60% can be received.
