Please do "file /dd/spmdriver".
Note the example code in the Device Driver Tutorial creates
a pseudo device node:
if (ddi_create_minor_node(dip, "0", S_IFCHR,
ddi_get_instance(dip), DDI_PSEUDO,0)!= DDI_SUCCESS)
For your hardware device type you should probably use DDI_NT_NET.
After a successful attach the device path should be "/dev/spm".
