Paolo Abeni 4d3365d5d3 Merge branch 'big-tcp-for-udp-tunnels' 
Alice Mikityanska says:

====================
BIG TCP for UDP tunnels

This series is a follow-up to "BIG TCP without HBH in IPv6", and it adds
support for BIG TCP IPv4/IPv6 workloads in vxlan and geneve. Now that
IPv6 BIG TCP doesn't require stripping the HBH in all various
combinations in tunneled traffic, adding BIG TCP becomes feasible.

Patch 01 adds accessors for the length field in the UDP header, as
suggested by Paolo in review. The usage of udp_set_len is then added in
the following patches that start using length=0 in BIG TCP UDP packets.

Patches 02-04 close the gaps that prevent BIG TCP packets from going
through UDP tunnel code.

Patch 05 validates packets in udp_gro_receive to exclude packets with
length=0 from GRO aggregation.

Patch 06 is for proper formatting in tcpdump (set UDP len to 0 rather
than a trimmed value on overflow).

Patches 07-08 bump up tso_max_size for VXLAN and GENEVE.

Patch 09 adds selftests.
