Bug description:
[Impact]
Intel I219 ethernet may wrongly detect 1Gbps network as 10Mbps after
ethernet cable hotplugging.
[Fix]
Use delayed work before deciding the network speed.
This essentially workarounds unreliable reading on MII_BMSR register.
[Test]
Before the patch the network operates at 10Mbps after cable gets
plugged.
With the fix, network always operates in 1Gbps.
[Regression Potential]
Low. It changes the watchdog task from timer to delayed work, the logic
is essentially the same.
