Bug description:
[SRU Justification]
[Impact]
Packets sent to a vti[6]/xfrm interface via bpf_redirect() or via an
AF_PACKET socket are dropped (no carrier).
This has been fixed in v5.5 by the following upstream commits
- 95224166a903 ("vti[6]: fix packet tx through bpf_redirect()")
- f042365dbffe ("xfrm interface: fix packet tx through bpf_redirect()")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=95224166a903
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f042365dbffe
The bug exists since the beginning of each driver.
== Fix ==
Backport the requested patches to Focal (5.4), Eoan (5.3), Bionic (4.15) and
Xenial (4.4).
== Risk of Regression ==
This patch affects only the cases described above (when no dst is
attached to the skb), thus the risk should be low.
