tunnel: Add layer 2 IPv6 GRE encapsulation support.
The patch adds ip6gre support. Tunnel type 'ip6gre' with packet_type=
legacy_l2 is a layer 2 GRE tunnel over IPv6, carrying inner ethernet packets
and encap with GRE header with outer IPv6 header. Encapsulation of layer 3
packet over IPv6 GRE, ip6gre, is not supported yet. I tested it by running:
# make check-kernel TESTSUITEFLAGS='-k ip6gre'
under kernel 5.2 and for userspace:
# make check TESTSUITEFLAGS='-k ip6gre'
