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 <jakub.kicinski@netronome.com> Reviewed-by: Simon Horman <simon.horman@netronome.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Acked-by: Amritha Nambiar <amritha.nambiar@intel.com> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
