[ofa-general] ***SPAM*** INT-X fallback in mthca driver

[subbu kl]

I am trying PCI passthrogh of Mellanox Infinihost III Lx chip based
Infiniband and TG3 ethernet PCIe cards on Centos 5.2 Full virtualized guest
with Xen 3.3.0

ib_mthca driver fails with
QUERY_FW failed
probe failed with errror -11

But interestingly tg3 driver says "Could not get MSI interrupts falling back
to INTx" and works fine

So,
1) why Xen could not get the MSI interrupts working ?
2) Should we have INT-x falling back method for Mellanox driver also if its
needed ?
