[PATCH 6.6 160/283] octeon_ep: support Octeon CN10K devices

Sasha Levin
2026-02-28T18:09:24Z

From: Shinas Rasheed <srasheed@marvell.com>

[ Upstream commit 0807dc76f3bf500f9a22465eedd2290da7357efb ]

Add PCI Endpoint NIC support for Octeon CN10K devices.
CN10K devices are part of Octeon 10 family products with
similar PCI NIC characteristics. These include:
- CN10KA
- CNF10KA
- CNF10KB
- CN10KB

Update supported device list in Documentation
