- Move endpoint code back up to BTL - Use opal_pointer_array_t for bounce buffer to identify local smsg completions. - Update and reenable sendi - Create a new endpoint for FMA/BTE transactions (keep local smsg/fma transactions seperate) - Move reverse get code into btl_ugni_put.c - Move eager get code into btl_ugni_get.c - Handle remote SMSG overruns correctly - Added support for inplace sends - etc This commit was SVN r26307.
