Yes this was one of the problems I discussed at LPC, please keep in mind
that I raised multiple other unrelated problems too.

In this project we discuss the debug-ability features only,
The orchestration features are a separate project that is still
on-going work to be under devlink.

We all agreed that devlink isn't the place for such vast device debug
options, hence this is our proposal, a separate aux device that works in 
unison with other aux devices such as virtio, vpda,rdma,netdev, etc ..

At netconf/KR I only discussed the orchestration project we are working
on to improve an going work we are doing, multi netdev interface, such
as the socket direct issue we discussed, this has nothing to do with 
this project proposal which cover RDMA,VDPA,netdev,virtio,Blue-Field,
etc .. ConnectX debug-ability and diagnosis problem.
