Subject: [PATCH v2 bpf-next 0/3] bpf: Add hwtstamp field for the sockops prog

From: Martin KaFai Lau <martin.lau@...nel.org>

The bpf-tc prog has already been able to access the
skb_hwtstamps(skb)->hwtstamp.  This set extends the same hwtstamp
access to the sockops prog.

v2:
- Fixed the btf_dump selftest which depends on the
  last member of 'struct bpf_sock_ops'.

Martin KaFai Lau (3):
  bpf: Add hwtstamp field for the sockops prog
  selftests/bpf: Fix incorrect ASSERT in the tcp_hdr_options test
  selftests/bpf: Test skops->skb_hwtstamp
