Subject: [PATCH net-next v4 0/6] introduce dropreasons in tcp receive path

From: Jason Xing <kernelxing@...cent.com>

As title said, we're going to refine the NOT_SPECIFIED reason in the
tcp v4/6 receive fast path.

This serie is another one of the v2 patchset[1] which are here split
into six patches. Besides, this patch is made on top of the previous
serie[2] I submitted some time ago.

Already got rid of @acceptable in tcp_rcv_state_process(), so I need to
remove *TCP_CONNREQNOTACCEPTABLE related codes which I wrote in the v3
series.

v3:

1. Split that patch into some smaller ones as suggested by Eric.

v2:
Link: https://lore.kernel.org/all/20240204104601.55760-1-kerneljasonxing@gmail.com/
1. change the title of 2/2 patch.
2. fix some warnings checkpatch tool showed before.
3. use return value instead of adding more parameters suggested by Eric.
Jason Xing (6):
  tcp: introduce another three dropreasons in receive path
  tcp: add more specific possible drop reasons in
