vxlan: Improve support for header flags
This patch cleans up the header flags of VXLAN in anticipation of defining some new ones: - Move header related definitions from vxlan.c to vxlan.h - Change VXLAN_FLAGS to be VXLAN_HF_VNI (only currently defined flag) - Move check for unknown flags to after we find vxlan_sock, this assumes that some flags may be processed based on tunnel configuration - Add a comment about why the stack treating unknown set flags as an error instead of ignoring them Signed-off-by:Tom Herbert <therbert@google.com> Signed-off-by:
