From 92c075dbdeed02bdf293cb0f513bad70aa714b8d Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Mon, 6 Jun 2016 22:50:39 +0200 Subject: net: sched: fix tc_should_offload for specific clsact classes When offloading classifiers such as u32 or flower to hardware, and the qdisc is clsact (TC_H_CLSACT), then we need to differentiate its classes, since not all of them handle ingress, therefore we must leave those in software path. Add a .tcf_cl_offload() callback, so we can generically handle them, tested on ixgbe. Fixes: 10cbc6843446 ("net/sched: cls_flower: Hardware offloaded filters statistics support") Fixes: 5b33f48842fa ("net/flower: Introduce hardware offload support") Fixes: a1b7c5fd7fe9 ("net: sched: add cls_u32 offload hooks for netdevs") Signed-off-by: Daniel Borkmann Acked-by: John Fastabend Signed-off-by: David S.
