ENGR00320136 net: fec: fix rcv is not last issue when do suspend/resume test
When do suspend/resume stress test, some log shows "rcv is not +last".
The issue is that enet suspend will disable phy clock, phy link down,
after resume back, enet MAC redo initial and ready to tx/rx packet,
but phy still is not ready which is doing auto-negotiation. When phy
link is not up, don't schdule napi soft irq.
