====================
Intel Wired LAN Driver Updates 2016-10-27

This series contains fixes to ixgbe and i40e.

Emil fixes a NULL pointer dereference when a macvlan interface is brought
up while the PF is still down.

David root caused the original panic that was fixed by commit id
(a036244c068612 "i40e: Fix kernel panic on enable/disable LLDP") and the
fix was not quite correct, so removed the get_default_tc() and replaced
it with a #define since there is only one TC supported as a default.

Guilherme Piccoli fixes an issue where if we modprobe the driver module
without enough MSI-X interrupts, then unload the module and reload it
again, the kernel would crash.  So if we fail to allocate enough MSI-X
interrupts, we should disable them since they were previously enabled.

Huaibin Wang found that the order of the arguments for
ndo_dflt_bridge_getlink() were in the correct order, so fix the order.
