Subject: [PATCH net-next 0/8] selftest: Extend tun/virtio coverage for GSO over UDP tunnels

This patch series increases test coverage for the tun/virtio use-case.

The primary goal is to add test validation for GSO when operating over 
UDP tunnels, a scenario which is not currently covered.

The design strategy is to extend the existing tun/tap testing infrastructure
to support this new use-case, rather than introducing a new or parallel framework.
This allows for better integration and re-use of existing test logic.

*** BLURB HERE ***

xu du (8):
  selftest: tun: Format tun.c existing code
  selftest: tun: Introduce tuntap_helpers.h header for TUN/TAP testing
  selftest: tun: Refactor tun_delete to use tuntap_helpers
  selftest: tap: Refactor tap test to use tuntap_helpers
  selftest: tun: Add helpers for GSO over UDP tunnel
  selftest: tun: Add test for sending gso packet into tun
  selftest: tun: Add test for receiving gso packet from tun
  selftest: tun: Add test data for success and failure paths
