Subject: [PATCH net-next v2 0/6] net/tcp: TCP-AO and TCP-MD5 tracepoints

Signed-off-by: Dmitry Safonov <0x7f454c46@...il.com>
---
Changes in v2:
- Fix the build with CONFIG_IPV6=m (Eric Dumazet)
- Move unused keyid/rnext/maclen later in the series to the patch
  that uses them (Simon Horman)
- Reworked tcp_ao selftest lib to allow async tracing non-tcp events
  (was working on a stress-test that needs trace_kfree_skb() event,
   not in this series).
- Separated selftest changes from kernel, as they now have a couple
  of unrelated to tracepoints changes
- Wrote a few lines of Documentation/
- Link to v1: https://lore.kernel.org/r/20240224-tcp-ao-tracepoints-v1-0-15f31b7f30a7@arista.com
