net/fec: fix pm to survive to suspend/resume
* in the actual driver, calling fec_stop and fec_enet_init doesn't allow to have a working network interface at resume (where a ifconfig down and up is required to recover the interface) * by using fec_enet_close and fec_enet_open, this patch solves this problem and handle the case where the link changed between suspend and resume * this patch also disable clock at suspend and reenable it at resume Signed-off-by: Eric Bénard <eric@eukrea.com> Signed-off-by: David S. Miller <davem@davemloft.net>
