The ERSPAN feature depends on the gre kernel module so on systems where
the ERSPAN feature isn't supported the openvswitch kernel module would
attempt to grab the ipv4 GRE protocol entry point and would fail to load

This patch modifies openvswitch to not fail to load when the gre kernel
module is loaded and instead it will print a warning message to the
kernel system log indicating that the ERSPAN feature may not be
available.
We need this patch because users are experiencing failures due to the
conflicts and high priority bugs are resulting.

Thanks William.
After loading the ip_gre and gre kernel modules you can run a 'make
check-kmod' test with those modules
loaded and the results look good as well.
