[RFC] ethdev: add send to kernel action

[Michael Savisko <michaelsav@nvidia.com>]

In some cases application may receive a packet that should have been
received by the kernel. In this case application uses KNI or other means
to transfer the packet to the kernel.
This commit introduces rte flow action that the application may use
to route the packet to the kernel while still in the HW.
