include functionalities such as Tx launch time (e.g. ETF and TAPRIO Qdiscs),
timestamping and policing.

Patch #1 - Introduce BPF helper
Patch #2 - Add test case (skb based)

Changes since v1:

 * Update changelog (Alexei Starovoitov)
 * Add test case (Alexei Starovoitov, Andrii Nakryiko)
 * Add missing function prototype (netdev ci)

Previous versions:
