[PATCH bpf-next v2 0/2] Add BPF-helper for accessing CLOCK_TAI

[Kurt Kanzenbach <kurt@linutronix.de>]

Hi,

add a BPF-helper for accessing CLOCK_TAI. Use cases for such a BPF helper
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:

 * v1: https://lore.kernel.org/r/20220606103734.92423-1-kurt@linutronix.de/
