Hi, I'm struggeling with an Ethernet driver on the FEC of a MPC860-T. To the best of my knowledge, I'm doing everything strictly as documented, and as other drivers do it. However, even when I just want to send a single packet (no interrrupts, everything as simple as possible), the package is sent 3 times to the wire; sometimes even 4 times. I don't see any indication of this in the software, just 3 packets on the wire, usually 5...9 us apart (on a 100 Mbps net; the packets come after 300...320 us on a 10 Mbps net).
Playing with half or full duplex mode didn't change anything. In case it matters: it's a LXT972LC PHY. Ummm.. and yes, I can be sure the hardware is working OK. It does so in another OS... Any ideas what I am missing?
