As discussed in http://lore.kernel.org/all/20250919013450.111424-1-xuanzhuo@linux.alibaba.com (local)
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
