====================
1GbE Intel Wired LAN Driver Updates 2015-12-14

This series contains updates to e1000e and igb.

Alex Duyck changes e1000_up() to void since it always returned 0, also
by making it void, we can drop some code since we no longer have to worry
about non-zero return values.

Aaron Sierra removes GS40G specific defines and functions since the i210
internal PHY can be accessed with the access functions shared by 82580,
i350 and i354 devices.  Also removes the code to add the PHY address into
the PCDL register address, since there is no real reason to do so.

Joe updates the cable length function reports all four pairs true min, max
and average cable length for i210.  Also updated ethtool to use enum-based
labels instead of hard coded values.

Benjamin Poirier cleans up code that is never reachable since MSI-X
interrupts are not shared in e1000e.  Also removes the ICR read in the
other interrupt handler, since the information is not needed and IMS is
configured such that the only link status change can trigger the other
interrupt handler.  Fixed in MSI-X mode, there is no handler for the LSC
interrupt so there is no point in writing that to ICS now that we always
assume other interrupts are caused by LSC.
