It can emulate a RTL8139C+ but you may want to edit hw/rtl8139.c and
uncomment the line containing

     #define RTL8139_ONBOARD_TIMER 1

Look at

http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PNid=14&PFid=6&Level=5&Conn=4

There are also drivers for several open source operating systems. Good
starting points are FreeBSD's if_rl and if_re drivers:

     http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/pci/if_rl.c

     http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/re/if_re.c

The later one requires that you uncomment the RTL8139_ONBOARD_TIMER
mentioned above.
