Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
1GbE Intel Wired LAN Driver Updates 2016-05-13

This series contains updates to e1000e, igb and igbvf.

Steve Shih fixes an issue for disabling auto-negotiation and forcing
speed and duplex settings for non-copper media.

Brian Walsh cleanups some inconsistency in the use of return variables
names to avoid confusion.

Jake cleans up the drivers to use the BIT() macro when it can, which will
future proof the drivers for GCC 6 when it gets released.  Cleaned up
dead code which was never being used.  Also fixed e1000e, where it was
incorrectly restting the SYSTIM registers every time the ioctl was being
run.

Denys Vlasenko fixes an oversight where incvalue variable holds a 32
bit value so we should declare it as such, instead of 64 bits.  Also
fixed an overflow check, where two reads are the same, then it is not
an overflow.

Nathan Sullivan fixes the PTP timestamps for transmit and receive
latency based on the current link speed.

Alexander Duyck adds support for partial GSO segmentation in the case
of tunnels for igb and igbvf.
