PUT and GET messages both target ME/MDs attached to portal 'portal_index' at
the destination - i.e. your question doesn't make sense
at the LNET protocol level.
However at the level of the lustre RPC, GETs are only used by servers fetching
bulk data for writes - i.e. the client has already
attached an ME/MD with unique matchbits (which it includes in the bulk RPC
request) the relevent ???_BULK_PORTAL. In actual fact, I
think it's only ever OST RCPs that do this currently.
