[openib-general] Tavor HCAs with openib

[Manpreet Singh]

Hi,

I was wondering if the Mellanox PCI-X cards (with
memory) are still supported in the openib stack.
Although the code seems to include it in the PCI
device id list, but I get the following error when I
load ib_mthca:

ib_mthca 0000:04:00.0: Missing UAR, aborting

Details of the configuration:

Kernel version: 2.6.12.3.
OpenIB kernel stack version: 3459 (from Sep 16).
HCA card device ID: 0x5a44.

The following is the PCI configuration space dump of
the HCA:

I'd appreciate any help/comments on this.

Thanks,
