Subject: [PATCH net-next v4 5/8] net: sched: add extack support for offload via tc_cls_common_offload
From: Quentin Monnet <quentin.monnet@...ronome.com>
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.
