Description

I see the following LNet Error in the logs:

2012-12-13 13:09:08 LNetError: 21195:0:(o2iblnd_cb.c:2261:kiblnd_passive_connect()) Can't accept 172.20.13.43@o2ib500 on NA (ib0:0:172.20.5.2): bad dst nid 172.20.5.2@o2ib500
2012-12-13 13:09:08 LNetError: 21180:0:(o2iblnd_cb.c:2261:kiblnd_passive_connect()) Can't accept 172.20.14.153@o2ib500 on NA (ib0:0:172.20.5.2): bad dst nid 172.20.5.2@o2ib500
2012-12-13 13:09:08 LNet: Added LNI 172.20.5.2@o2ib500 [8/1024/0/180]
2012-12-13 13:09:09 LNET configured

Without looking at the code, it seems like LNet is denying the incoming connection because it is not yet configured. If that is the case, I don't think that warrants a console message. It should just silently refuse the connection until it is fully configured.
