[ofa-general] cmatose fails whereas rping passes on iWarp

[pandit ib]

peer2peer setting made a difference.
I'm not getting the connect errors any more.

However, there is still some difference in behavior between running on
IB vs iWarp.
In IB's case the test completes but over iWarp's both sides hang (no
connect errors this time though)

on iWarp:

[root at lv4 examples]# ./ucmatose
'cmatose: starting server
initiating data transfers
completing sends
--> Hangs here

[root at lv5 examples]# ./ucmatose -s 192.168.10.33
cmatose: starting client
cmatose: connecting
receiving data transfers
sending replies
data transfers complete
--> Hangs here
