I'm confused, kernel has this header file
include/uapi/linux/openvswitch.h, but ovs also has this header file
datapath/linux/compat/include/linux/openvswitch.h, both of them included
this enumeration definition:
enum {
OVS_VXLAN_EXT_UNSPEC,
OVS_VXLAN_EXT_GBP, /* Flag or __u32 */
__OVS_VXLAN_EXT_MAX,
};
Don't we need to make sure they are consistent with the below line?
OVS_VXLAN_EXT_GPE, /* Flag, Generic Protocol Extension */
