commit 80a0ceb46d8bf80d9c2d7e5dc4ed73a3dddf852d
Author: Rubasri Kalidas <rubasri.kalidas at intel.com>
Date:   Tue Jul 19 14:19:46 2016 -0500

    CH4: Fix persistent send/recv hangup issue
    
    Initialize source rank in recv init which results in proper rank being
    returned in startall. As a result, proper receive is posted and the
    request gets completed.
    
    fixes csr/mpich-opa#340
