Dell PowerEdge uses Intel NIC E610 and if this nic is planned to be used for PXE boot and to access the internet this missing functionality will effectively disqualify those servers from the approved HW for Openstack since NIC will not be detected by the OS.

> The regression risk is low. There are no core kernel changes. Changes are primarily to the ixgbe driver (drivers/net/ethernet/intel/ixgbe/) adding support for the Intel E610 device. The majority of the changes are in newly added files (ixgbe_e610.c ixgbe_type_e610.h). There are some minor refactoring to existing ixgbe code involving the x540 and x550 nics but existing device behavior isn't changed it's just shared with E610.
