From f7be70e5130e35a0ee5434e8e7a6d3288c86f94a Mon Sep 17 00:00:00 2001 From: Jerin Jacob Date: Sun, 8 Oct 2017 18:14:15 +0530 Subject: [PATCH] net/octeontx: add net device probe and remove An octeontx ethdev device consists of multiple PKO VF devices, a PKI VF device and multiple SSOVF devices which shared between eventdev. This patch adds a vdev based device called "eth_octeontx" which will create multiple ethernet ports based on "nr_port" or maximum physical ports are available in the system.
