Infiniband subnetmanager and driver compilation on FreeBSD 10.1

[Mihai Vintila]

Hi,
I've posted in the stable mailing list but i guess this is where i 
should ask.
Can you tell me what is the proper way to get subnet manager working on 
FreeBSD 10.1 ?
I've used RELEASE branch to compile opensm and drivers from Mellanox but 
i get:
ibportstate -G 0xe61d2dfffe0a2130 1 enable
ibpanic: [868] madrpc_init: can't open UMAD port ((null):0): (m)
