Actually, it should not print any message at all.
pci_enable_msi() failure is a normal event (as you point out). Even
at KERN_INFO level, the message is still misleading.
I've been reworking some of this code and there is even a
pci_disable_msi() missing in case pci_request_irq failed. I'll post a
patch to clean it up in a second.
It seems ixgb needs this too (the message removal at least?)
yes, I'll get there once I get a chance to get some e1000 work near completion
first. I don't think that for ixgb this is as big of a deal for now. If MSI is
breaking with a 10gig adapter I think people appreciate the error.
We do have to make sure that the PCI subsystem throws errors in the case it is
justified, like when we're out of vectors, or something really bad happens
(perhaps suspend/resumish). I assume that is the case, but I haven't checked.
