From b7051cb8dadd69f85da5989017af2bb35b418950 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 23 Jan 2018 00:08:40 -0800 Subject: i40e: flower: check if TC offload is enabled on a netdev Since TC block changes drivers are required to check if the TC hw offload flag is set on the interface themselves. Fixes: 2f4b411a3d67 ("i40e: Enable cloud filters via tc-flower") Fixes: 44ae12a768b7 ("net: sched: move the can_offload check from binding phase to rule insertion phase") Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Acked-by: Jiri Pirko Acked-by: Amritha Nambiar Acked-by: Jeff Kirsher Signed-off-by: David S.
