if_re freebsd driver, adapted for the build by Francesco Piccinini. It

supports many Realtek based NIC which our own driver doesn't support 
(for example the RTL8101E). Thanks! Not added to the image yet, since it 
causes some problems on my laptop (but could well be caused by the 
freebsd compat layer, or by the scheduler)
