The current admin function (AF) driver and the netdev driver supports
OcteonTx2 silicon variants. The same OcteonTx2's
Resource Virtualization Unit (RVU) is carried forward to the next-gen
silicon ie OcteonTx3, with some changes and feature enhancements.

This patch set adds support for OcteonTx3 (CN10K) silicon and gets
the drivers to the same level as OcteonTx2. No new OcteonTx3 specific
features are added.

Changes cover below HW level differences
- PCIe BAR address changes wrt shared mailbox memory region
- Receive buffer freeing to HW
- Transmit packet's descriptor submission to HW
- Programmable HW interface identifiers (channels)
- Increased MTU support
- A Serdes MAC block (RPM) configuration

v3-v4
Fixed compiler warnings.

v2-v3
Reposting as a single thread.
Rebased on top latest net-next branch.

v1-v2
Fixed check-patch reported issues.

Still 4 new sparse warnings in patch 1.

Thanks Jakub. Overlooked new warnings as I was using C=2 flag.
Will fix it in the next version.
