Subject: [RFC, net-next v0 0/2] Microsemi PHY cable

This series of patches add the Microsemi PHY cable diagnostics command 
with PHY Netlink Interface.

1. phy_netlink.c and phy_netlink.h files add for PHY diagnostics features
implementation through PHY Netlink interface.
2. phy.c contain the generic functions of "PHY diagnostics". This layer
independ of the communication layer (i.e. Netlink or IOCTL etc)
3. mscc.c contain the 4-pair ethernet PHY driver along with
PHY diagnostics feature.

Patches test on VSC8531 Microsemi PHY - Beaglebone Black target

Test results:
------------
# nl-app eth0 request
GroupID = 2
GroupName = phy_monitor

Cable Diagnostics Request:
Operation Status : Success
Cable Pairs mask : 0xf
Timeout count    : 84
Cable diagnostics results:
    Pair A: Correctly terminated pair, Loop Length: 0 m
    Pair B: Correctly terminated pair, Loop Length: 0 m
    Pair C: Correctly terminated pair, Loop Length: 0 m
    Pair D: Correctly terminated pair, Loop Length: 0 m
