is this supposed to work at the moment? When I try, the machine seems to crash:

root@one:~ # sysctl sys.device.mlx4_core0.mlx4_port1=eth
sys.device.mlx4_core0.mlx4_port1: auto (ib)
Write failed: Broken pipe
Shared connection to xxx closed.

Unfortunately I don't have serial console access at the moment, so I can't access any messages that may have gotten dumped.

The cards in question are:

mlx4_core0@pci0:17:0:0:	class=0x028000 card=0x005015b3 chip=0x100315b3 rev=0x00 hdr=0x00
    vendor     = 'Mellanox Technologies'
    device     = 'MT27500 Family [ConnectX-3]'
    class      = network

Lars
