Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next

Jeff Kirsher says:

====================
This series contains updates to ixgbe, igb and pci.

The ixgbe changes contains a fix to a possible divide by zero by bailing
out of the ixgbe_update_itr() function if the last interrupt timeslice is
zero.  In addition, support is added for the new OCP x520 adapter as well
as LX support for 82599 devices.  Jacob provides a patch to change
variable wol_supported to wol_enabled to better reflect what the code
is actually doing (i.e. checking if WoL is enabled).

Alex adds SRIOV helper function to pci that will determine if a PF
has any VFs that are currently assigned to a guest.

The remaining 8 patches are against igb and contain the following changes:
* implement SERDES loopback configuration for i210 devices by unsetting
  sigdetect bit, so as to fix Ethtool loopback test failure
* add support for the SMBI semaphore for I210/I211 devices
* implement the new generic pci_vfs_assigned helper function (Alex's PCI
  helper function)
* display warning when link speed is downgraded due to Smartspeed
* ensure that VLAN hardware filtering remains enabled when the device is
  in promiscuous mode and VT mode simultaneously
* cleanup dead code in igb
* bump the driver version

v2: updated the PCI patch to add SRIOV helper function to remove extern
    from the declaration of pci_vfs_assigned in pci.h and return 0 if
    SR-IOV is disabled which is inline with other PCI SR-IOV functions
