net: mpls: make function ipgre_mpls_encap_hlen static

The function ipgre_mpls_encap_hlen is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: symbol 'ipgre_mpls_encap_hlen' was not declared. Should it be static? Fixes: bdc4764 ("ip_tunnel: add mpls over gre support") Signed-off-by: Colin Ian King <[email protected]> Acked-by: David Ahern <[email protected]> Signed-off-by: David S.
