r8169: restore mac addr in rtl8169_remove_one and rtl_shutdown
The newer chipsets (all PCI-E) are known that they need full power cycle (AC or battery removal) to reset MAC address to a hardwired one. Previous patch to address this problem loads the original MAC address from EEPROM. But it brought other problem for which it is necessary to introduce a new module parameter. However, it might suffice to restore the initial MAC address before shutdown/reboot/kexec and when removing the module. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.
