pcnet: Add link state support
Update lnkst on link state changes so that guests can obtain this information via reading back the LED output pin. Works for Linux but not for guests that depend on the missing PHY. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
