LID reconfiguration

Hello,

I'm working on making an application multi-path aware and at the same time
we would like to make it resilient to the SM restarting and reassigning
LIDs. We use a special multicast address to discover other nodes on the
network and then MAD to get full path information. The application is
written directly to verbs and establishes reliable connections using
information exchanged over ARP.

Is there anything I can do other than restart the discovery and connection
process? Shouldn't we have enough information with the GID to retain and
reroute the connection?

One more question; I saw librdmacm which looked nice but it does not
support multi-path connections. It would eliminate a lot of code if we
could use this, are there plans for it? Did I miss some functionality?

Thanks,
Jeff
