Subject: [PATCH net v4 0/4] 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.


Thanks.

v4:
   1. add commit "virtio-net: Ensure hdr_len is not set unless the header is forwarded to the device." @Jason

v3:
   1. recode the #3 for tunnel gso, and test it



Xuan Zhuo (4):
  virtio-net: fix incorrect flags recording in big mode
  virtio-net: Ensure hdr_len is not set unless the header is forwarded
    to the device.
  virtio-net: correct hdr_len handling for VIRTIO_NET_F_GUEST_HDRLEN
  virtio-net: correct hdr_len handling for tunnel gso
