libibverbs: Update examples for IBoE
PATCH v8 4/4 libibverbs: Update examples for IBoE
Since IBoE requires usage of GRH, update ibv_*_pinpong examples to accept GIDs. GIDs are given as an index to the local port's table and are exchanged between the client and the server through the socket connection. The examples are also modified to pass the gid index to the code that creates the address vector as a preparation to using gids other the the on in index 0.
