====================
Intel Wired LAN Driver Fixes 2019-03-26

This series contains updates to igb, ixgbe, i40e and fm10k.

Jake fixes an issue with PTP in i40e where a previous commit resulted
in a regression where the driver would interpret small negative
adjustments as large positive additions, resulting in incorrect
behavior.

Arvind Sankar fixes an issue in igb where a previous commit would cause
a warning in the PCI pm core and resulted in pci_pm_runtime_suspend
would not call pci_save_state or pci_finish_runtime_suspend.

Ivan Vecera fixes MDIO bus registration with ixgbe, where the driver was
ignoring errors returned when registering and would leave the pointer in
a NULL state which triggered a BUG when un-registering.

Stefan Assmann fixes the check for Wake-On-LAN for i40e, which only
supports magic packet.

Yue Haibing fixes a potential NULL pointer de-reference in fm10k by
adding a simple check if the value is NULL.
