From 8f0b425a712b82732127ff7880f92504f20fcc11 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Fri, 19 Jan 2018 17:44:47 -0800 Subject: net: sched: add extack support for offload via tc_cls_common_offload Add extack support for hardware offload of classifiers. In order to achieve this, a pointer to a struct netlink_ext_ack is added to the struct tc_cls_common_offload that is passed to the callback for setting up the classifier. Function tc_cls_common_offload_init() is updated to support initialization of this new attribute. Signed-off-by: Quentin Monnet Reviewed-by: Jakub Kicinski Signed-off-by: David S.
