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")
