Greetings:
Welcome to v4.
This series fixes netdevsim to correctly set the NAPI ID on the skb.
This is helpful for writing tests around features that use
SO_INCOMING_NAPI_ID.
In addition to the netdevsim fix in patch 1, patches 2 & 3 do some self
test refactoring and add a test for NAPI IDs. The test itself (patch 3)
introduces a C helper because apparently python doesn't have
socket.SO_INCOMING_NAPI_ID.
Thanks,
Joe

- Updated the macro guard in patch 2
- Removed the remote deploy from patch 3

- Dropped patch 3 from v2 as it is no longer necessary.
- Patch 3 from this series (which was patch 4 in the v2)
- Sorted .gitignore alphabetically

- Dropped the NetNSEnter as it is unnecessary
- Fixed a string interpolation issue that Paolo hit with his Python
version
v2: https://lore.kernel.org/netdev/20250417013301.39228-1-jdamato@fastly.com/
