I am looking for some help real soon as I ran into this problem with the HDLC driver for a MPC860 processor. I coded the driver in BSD 4.3 style. The problem I am noticing is as follows:
I can attach the driver to the network layer using if_attach() call and I also initialize the hardware (i.e. SCC2 for HDLC mode). I can see the interface when I do ifShow from the shell. It has everything except the MAC address. However, when I tried to send a ping to the interface I get the mbuf handed to my output routine, but the interface structure send queue is empty. I would appreciate if you folks can let me know if I need to do any other initialization other than if_attach()/ether_attach() and my own hardware initialization. I would be happy to send my code for you folks to take a look. I appreciate your help.
