I thought it's not required to wait API was fixed and committed.
To support only MSI is easy, but MSI-X is not. This commit includes not
only pci_intr_establish() stuff but also include other MSI-X stuff to setup
MSI-X vector table and interrupt related functions. And, it'll take time
to check regression or stability to make it enable by default, so it's
important other people to test with it.
The same work will be required for RAID controllders' drviers.
Thanks.
