ehea: set mac address fix
eHEA has to call firmware functions in order to change the mac address of a logical port. This patch checks if the logical port is up when calling the register / deregister mac address calls. If the port is down these firmware calls would fail and are therefore not executed. Signed-off-by: Jan-Bernd Themann <themann@de.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
