This patch adds netdev interface for SDP VFs. This interface can be used
to communicate with a host over PCIe when OcteonTx is in PCIe Endpoint
mode.

All your SDP/SDK/management interfaces do not fit into our netdev
model of the world and should be removed upstream.

SDP is our System DMA Packet Interface which sends/receives network
packets to NIX block. It is similar to CGX, LBK blocks but only
difference is the medium being PCIe. So if you have accepted that I
believe you can accept this as well.

Nope, I have not accepted that. I was just too lazy to send a revert
after it was merged.

What is the objection here ?
Is kernel netdev not supposed to be used with-in end-point ?
If customers want to use upstream kernel with-in endpoint and not
proprietary SDK, why to impose restrictions.

Thanks,
Sunil.
