This patchset adds support for SRv6 Headend behavior with Reduced
Encapsulation. It introduces the H.Encaps.Red and H.L2Encaps.Red versions
of the SRv6 H.Encaps and H.L2Encaps behaviors, according to RFC 8986 [1].
In details, the patchset is made of:
- patch 1/4: add support for SRv6 H.Encaps.Red behavior;
- Patch 2/4: add support for SRv6 H.L2Encaps.Red behavior;
- patch 2/4: add selftest for SRv6 H.Encaps.Red behavior;
- patch 3/4: add selftest for SRv6 H.L2Encaps.Red behavior.
The corresponding iproute2 patch for supporting SRv6 H.Encaps.Red and
H.L2Encaps.Red behaviors is provided in a separated patchset.

V4 -> v5:
- Fix skb checksum for SRH Reduced encapsulation/insertion;
- Improve selftests by:
i) adding a random suffix to network namespaces;
ii) creating net devices directly into network namespaces;
iii) using trap EXIT command to properly clean up selftest networks.
Thanks to Paolo Abeni.
v3 -> v4:
- Add selftests to the Makefile, thanks to Jakub Kicinski.
v2 -> v3:
- Keep SRH when HMAC TLV is present;
- Split the support for H.Encaps.Red and H.L2Encaps.Red behaviors in two
patches (respectively, patch 1/4 and patch 2/4);
- Add selftests for SRv6 H.Encaps.Red and H.L2Encaps.Red.
v1 -> v2:
- Fixed sparse warnings;
- memset now uses sizeof() instead of hardcoded value;
- Removed EXPORT_SYMBOL_GPL.
