[PATCH net-next 1/2] openvswitch: Allow GRE ports when compiled as a module.

[PATCH net-next 1/2] openvswitch: Allow GRE ports when compiled as a module.

[Jesse Gross]

Open vSwitch GRE tunnels are currently only enabled if the GRE
datapath code is statically compiled in but it should be possible
to use it as a module as well.

[PATCH net-next 2/2] ip_tunnel: Protect tunnel functions with CONFIG_INET guard.

[Jesse Gross]

Tunnel constants can be used in generic code but in these cases
the inline functions in ip_tunnels.h cause compilation problems
if CONFIG_INET is not set.

Pravin's copy of this same exact patch hit my inbox first, so I applied
his.  Thanks.
