[PATCH net-next v2 1/2] net: macb: Poll for link state changes when using the internal PCS.

[Nathan Whitehorn <nwhitehorn@pa.msu.edu>]

There is current support for signalling to software when this changes
via an interrupt etc., so poll once per second. This is required when
there is no external PHY (including an SGMII-attached PHY) to convey
link state information to the MAC.
