Does mlxen work on FreeBSD 10.1 with ConnectX-3

[Vadim Alimov]

Yeah, there are mlxen0 and mlxen1 devices, but they are "no carrier" 
whatever i do.
As I guess, there are two possible reasons:
1) the qsfp cable i use is incompatible (has a wrong firmware) with 
mellanox chip
2) freebsd driver does not work

I'll try to setup linux. If it goes the same i'll have to order native 
mellanox cable.

I'll write you down the results. Thanks.

Regards, Vadim.
