[openib-general] Low cost MBs compatible with Mellanox PCIE Cards

[Steve Welch]

The HCA shows x8 on the A8N32-SLI Deluxe:

                Link: Supported Speed 2.5Gb/s, Width x8, ASPM L0s, Port 8
                Link: Latency L0s unlimited, L1 unlimited
                Link: ASPM Disabled RCB 64 bytes CommClk- ExtSynch-
                Link: Speed 2.5Gb/s, Width x8

Glad to hear you have the MSI problem taken care of.

Steve
