Wesley,

Only an issue if someone wants to use the MCX3* cards

Martyn, Rich,

This may be a little late to the party, but I'd like to chime in that the MHQH29C-XTR works beautifully on Open Indiana.  The hermon driver attaches, IPoIB works, as does SRP.  I answer this question because I was attempting to research this very subject, and found a scarcity of information on this.

ibp1         2C9030057B3E0   2C9030057B3E2   2    down   FFFF

Additional notes for other members of the list: 
    * 'memfree' InfiniHost III cards such as the MHEA28-XTC do not work at all with Open Indiana.
    * if you are wanting a vintage and affordable card, the 128MB version of the above card such as the MHGA28-1TC should work.  I am getting one in soon for testing.

I have a ConnectX based card the works fine with the hermon driver in oi_148, but I have been unable to find any information about Solaris or OpenIndiana support for any of the ConnectX 2 HCAs. I was hoping someone might be using the card (or any of the other PCI device ID 26428 cards  http://www.mellanox.com/content/pages.php?pg=firmware_table_ConnectX2IB
) and can confirm compatibility?
