mpls_iptunnel is used only for mpls encapsuation, and if encaplusated
packet is larger than MTU we need mpls_gso for segmentation.

Then CONFIG_MPLS_IPTUNNEL should probably select CONFIG_NET_MPLS_GSO.
Currently, one can build mpls_iptunnel.ko without mpls_gso.ko.

Also, MPLS encapsulation can also be done with act_mpls.ko. So this
module should probably have this softdep too (and the Kconfig
dependency).
