From 0b9de4ca853b6ba2c92ff0b4602281001b166639 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 7 Feb 2018 20:55:23 -0800 Subject: nfp: don't advertise hw-tc-offload on non-port netdevs nfp_port is a structure which represents an ASIC port, both PCIe vNIC (on a PF or a VF) or the external MAC port. vNIC netdev (struct nfp_net) and pure representor netdev (struct nfp_repr) both have a pointer to this structure. nfp_reprs always have a port associated. nfp_nets, however, only represent a device port in legacy mode, where they are considered the MAC port. In switchdev mode they are just the CPU's side of the PCIe link. By definition TC offloads only apply to device ports. Don't set the flag on vNICs without a port (i.e. in switchdev mode).
