It is possible (and acutally prety well supported)  to  have  multipe
ethernet  interfaces,  but  of  course  this  requires  corresponding
support on the driver level.

Your description is so inaccurate that it is impossible even to guess
what you mean; for example you write  "by  typing  eth1  or  eth2  to
switch  between  the  ethernet  ports"???  No  such text can be found
anywhere in any available documentation.

Yes, of course it is. But definitely NOT "by typing eth1 or eth2" :-(
