[net-next 00/11][pull request] 1GbE Intel Wired LAN Driver Updates 2017-06-06

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

This series contains updates and fixes to e1000e and igb.

Matwey V Kornilov fixes an issue where igb_get_phy_id_82575() relies on
the fact that page 0 is already selected, but this is not the case after
igb_read_phy_reg_gs40g()/igb_write_phy_reg_gs40g() were removed in a
previous commit.  This leads to initialization failure and some devices
not working.  To fix the issue, explicitly select page 0 before first
access to PHY registers.

Arnd Bergmann modifies the driver to avoid a "defined but not used"
warning by removing #ifdefs and using __maybe_unused annotation instead
for new power management functions.

Jake provides most of the changes in the series, all around PTP and
timestamp fixes/updates.  Resolved several race conditions based on
the hardware can only handle one transmit timestamp at a time, so
fix the locking logic, as well as create a statistic for "skipped"
timestamps to help administrators identify issues.

Benjamin Poirier provides 2 changes, first to igb to remove the
second argument to igb_update_stats() since it always passes the
same two arguments.  So instead of having to pass the second argument,
just update the function to the necessary information from the adapter
structure.  Second modifies the e1000e_get_stats64() call to
dev_get_stats() to avoid ethtool garbage being reported.

Konstantin Khlebnikov modifies e1000e to use disable_hardirq(), instead
of disable_irq() for MSIx vectors in e1000_netpoll().

The following are changes since commit 9d15e5cc8cb68326f7f89b76e04c834fe8e1a2db:
  mdio: mux: fix an incorrect less than zero error check using a u32
