Subject: [PATCH v2 net-next 0/2] add more drop reasons in tcp receive path

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

When I was debugging the reason about why the skb should be dropped in
syn cookie mode, I found out that this NOT_SPECIFIED reason is too
general. Thus I decided to refine it.

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 (2):
  tcp: add more DROP REASONs in cookie check
  tcp: add more DROP REASONs in receive process
