Mellanox NIC names changed, each kldunload/kldload mlx4ib module

[Alex Liptsin]

Hi.

I work with FreeBSD9.1 and Mellanox devices.
Every time I unload / load mlx4ib module, NIC names of mellanox devices (ibX) are renamed.
Can I prevent it?

[root at h-qa-032 mlx4]# ifconfig
ib8: flags=8002<BROADCAST,MULTICAST> metric 0 mtu 65520
        options=80018<VLAN_MTU,VLAN_HWTAGGING,LINKSTATE>
        lladdr 80.28.0.48.fe.80.0.0.0.0.0.0.0.2.c9.3.0.2e.48.31
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
ib9: flags=8002<BROADCAST,MULTICAST> metric 0 mtu 65520
        options=80018<VLAN_MTU,VLAN_HWTAGGING,LINKSTATE>
        lladdr 80.28.0.49.fe.80.0.0.0.0.0.0.0.2.c9.3.0.2e.48.32
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
