Subject: [PATCH net v1 0/3] fixes two virtio-net related bugs.

As discussed in http://lore.kernel.org/all/20250919013450.111424-1-xuanzhuo@linux.alibaba.com
Commit #1 Move the flags into the existing if condition; the issue is that it introduces a
small amount of code duplication.

Commit #3 is new to fix the hdr len in tunnel gso feature.

Hi @Paolo Abenchi,
Could you please test commit #3? I don't have a suitable test environment, as
QEMU doesn't currently support the tunnel GSO feature.

Thanks.

Xuan Zhuo (3):
  virtio-net: fix incorrect flags recording in big mode
  virtio-net: correct hdr_len handling for VIRTIO_NET_F_GUEST_HDRLEN
  virtio-net: correct hdr_len handling for tunnel gso
