Along this line of though:  phy_connect requires struct net_device, which has a struct net_device_ops within it.  When I do a phy_connect am I supposed to provide the minimal functions for netdev_ops (correct this list if I am mistaken):
ndo_open
ndo_stop
ndo_start_xmit
ndo_get_stats
ndo_set_multicast_list
As well as populate the dev->dev_addr within the struct net_device.

The part that confuses me is that the smsc.c ??driver?? under drivers/net/phy/smsc.c doesn’t do any of this.  This is a phy supported by this file, so should I have to do all this to get the device up?

Spinning,
Andy
