Hi Folks,

For the GNI provider we could implement srx context.  Basically you'd end
up binding the tag matching engine to multiple endpoints.   But we are
quite busy getting the GNI provider ready for 1.5 release and KNL
optimizations so I doubt we'd have cycles to implement srx context in time
for the 1.5 release. We may have cycles to implement for a 1.6 release if
there's a compelling use case.

For now, you'd probably be better of with the GNI provider using FI_EP_RDM
and the AV.
