Hi All.
I'm interesting of mellanox ConnectX-3 cards that support VPI.
As a read from
http://www.openfabrics.org/downloads/OFED/ofed-1.4/OFED-1.4-docs/mlx4_release_notes.txt
VPI provide ability to autodetect link type or control which type to
use. But does it possible to have on one port 10Gb ethernet and
infiniband together?

However, you can run IB applications over an ETH link layer by using RoCE (RDMA over Converged Ethernet). If you do: ibv_devinfo on a host where an HCA has a port configured to an ETH link layer, you should see an entry for the ETH layer port.
