prov/net: Set counter inc callback for saved receives
Browse files Browse the repository at this point in the history
If a posted receive matches with a saved receive, we may need to
increment the rx counter.  Set the rx counter increment callback
to match that of the posted receive.  This fixes an assert in
xnet_cntr_inc() accessing a NULL cntr_inc function pointer.

Program received signal SIGABRT, Aborted.
