This set adds various BPF helper improvements, that is, cleaning
up and adding BPF_F_CURRENT_CPU flag for tracing helper, allowing
for preemption checks on bpf_get_smp_processor_id() helper, and
adding two new helpers bpf_skb_change_{proto, type} for tc related
programs. For further details please see individual patches.Note, this set requires -net to be merged into -net-next tree first. Thanks a lot!
