[PATCH net 0/3] ipgre: fix lwtunnel support

lwtunnels currently work only with gretap. This patchset fixes the bugs in
ipgre metadata mode implementation.

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.

Jiri Benc (3):
gre: do not assign header_ops in collect metadata mode
gre: build header correctly for collect metadata tunnels
gre: receive also TEB packets for lwtunnels
