net: mpls: Increase max number of labels for lwt encap
Alow users to push down more labels per MPLS encap. Similar to LSR case, move label array to the end of mpls_iptunnel_encap and allocate based on the number of labels for the route. For consistency with the LSR case, re-use the same maximum number of labels. Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
