Description
MPLS is supported in linux kernel since 4.3, however it seems its not supported in WSL kernel.
I have been using WSL2 for testing MPLS features, however i am getting the below errors, i am testing with Juniper cRPD which works well in terms of Ip routing on WSL, however MPLS isn't working, there are other features like MS SONiC which will be impacted by non-support of MPLS.
Appreciate any support to resolve the issue.

Research direction
Start by examining the WSL2 kernel configuration and module availability for mpls_router and mpls_iptunnel, using the reported modprobe failures as the baseline. Done should mean those modules load on the reported WSL2 kernel and MPLS features work for the described routing use case.
