Yeah the patch (attached) is very simple and applies to v1.3 without any
problem.

Note that it also adds port numbers to non-IB/OFED devices. When I
switch a ConnectX board to ethernet, I get:

      PCI 15b3:634a (P#49152 busid=0000:0c:00.0 class=0c06(IB) PCIVendor="Mellanox Technologies" PCIDevice="MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE]") "Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE]"
        Net L#3 (Address=00:00:00:11:11:11 Port=1) "eth3"
        Net L#4 (Address=00:00:00:11:11:12 Port=2) "eth4"

That looks good to me, as long as starting port numbers to 1 for
non-IB/OFED is OK.
