Subject: [PATCH net v2 0/3] gre: fix lwtunnel support

This patchset fixes a few bugs in gre metadata mode implementation, mainly
with ipgre.

As an example, in this setup:

ip a a 192.168.1.1/24 dev eth0
ip l a gre1 type gre external
ip l s gre1 up
ip a a 192.168.99.1/24 dev gre1
ip r a 192.168.99.2/32 encap ip dst 192.168.1.2 ttl 10 dev gre1
ping 192.168.99.2

the traffic does not go through before this patchset and does as expected
with it applied.

v2: Rejecting invalid configuration, added patch 3, dropped patch for
    ETH_P_TEB (will target net-next).

Jiri Benc (3):
  gre: do not assign header_ops in collect metadata mode
  gre: build header correctly for collect metadata tunnels
  gre: allow creation of gretap interfaces in metadata mode
