ib_umad module?

[James Pan]

Hi,I have installed Mellanox's latest driver (MLNX_EN_FreeBSD_v2.1) and it seems the device is recognized.I also build the ofed tools from /usr/src/contrib/ofed but when I try to run ibstat it prints the following message:
root at c4:~ # ibstat ibwarn: [30785] umad_init: can't read ABI version from /sys/class/infiniband_mad/abi_version (m): is ib_umad module loaded?ibpanic: [30785] main: can't init UMAD library: (m)
Do I miss something? Thanks! 
Best Regards,
