--- Comment #3 from Vladislav V. Prodan <admin@support.od.ua> ---
After reading the article https://wiki.freebsd.org/InfiniBand, I realized my
error.

I unload the old modules in the memory .
Rebuild the world to FreeBSD 10.2-STABLE # 0: Fri Jan 8, 2016 18:45:13 EET
And added to the kernel options
options        OFED            # Infiniband protocol stack and support
options        SDP             # Sockets Direct Protocol for infiniband
options        IPOIB_CM        # Use connect mode ipoib
device         ipoib           # IP over IB devices
device         mlx4ib          # ConnectX Infiniband support
device         mlxen           # ConnectX Ethernet support
device         mthca           # Infinihost cards

After these manipulations network card recognized by the system, it is now
possible to change the IP and MTU.
