I guess the relevant people will be there from the RNIC vendors, but
this seems more like an IETF/rdma consortium issue to me.

Maybe we can try to brainstorm for alternate solutions, but it seems
we are missing all the key stakeholders from the Linux networking
side to really resolve this.

I haven't seen any discussion of this yet.  Is it really worth taking
up face-to-face time on this?  It seems like it should all be pretty
straightforward, and even if it isn't, we haven't spent the time to
figure out what the not straightforward parts are yet.

Again, I haven't seen any discussion yet, so it doesn't seem worth
taking up face-to-face-time until we know what the sticking points are.
