Subject: net: Make mpls_entry_encode() available for generic users
Patch-mainline: v5.8-rc1
Git-commit: 86ae579cefffe18cb08928505d90fbc87367e8f5
References: jsc#SLE-15172
Move mpls_entry_encode() from net/mpls/internal.h to include/net/mpls.h
and make it available for other users. Specifically, hardware driver that
offload MPLS can benefit from that.
