smsc_attach_post()

static void smsc_attach_post ( struct usb_ether *  ue )

smsc_attach_post - Called after the driver attached to the USB interface @ue: the USB ethernet device

This is where the chip is intialised for the first time. This is different from the smsc_init() function in that that one is designed to setup the H/W to match the UE settings and can be called after a reset.
