From 6d59e4ea74a6dfaa70035b858257c9694f9ed242 Mon Sep 17 00:00:00 2001 From: "Chen Jing D(Mark)" Date: Fri, 13 Jan 2017 11:13:18 +0800 Subject: [PATCH] net/i40e: change version number to support Linux VF i40e PF host only support to work with DPDK VF driver, Linux VF driver is not supported. This change will enhance in version number returned. Current version info returned won't be able to be recognized by Linux VF driver, change to values that both DPDK VF and Linux driver can recognize. The expense is original DPDK host specific feature like CFG_VLAN_PVID and CONFIG_VSI_QUEUES_EXT will not available. DPDK VF also can't identify host driver by version number returned. It always assume talking with Linux PF.
