Initializing networking

[David Dudley]

I attempted to change the interface, by going in to the bsp.h file, and
changing tsec2 to tsec1 (and vice versa), but it still insists in using
tsec2.  Is the unit number set somewhere separate from the name?

To activate the switch, I just loaded the firmware from within the u-bot
monitor (the same and Linux does), and then loaded RTEMS.  However, I cannot
find tsec1 anywhere on the network interfaces lists, regardless of how I
configure rtems_bsdnet_config.  It seems that the configuration I generate
is ignored, and some default internal list is used instead.
