Subject: interrupt handling in the new aquantia ethernet driver

Hi David,

commit a4d36e20 ("net: ethernet: aquantia: PCI operations") adds some
realy odd interrupt related code, including a call to the long
gone pci_enable_msix() function.  I first wondered how this compiles.
but the code happens to be under

#if AQ_CFG_FORCE_LEGACY_INT

where AQ_CFG_FORCE_LEGACY_INT is defined to 0U, so it isn't compiled in,
although probably not intentionally.  

It would be good to a) kill that ifdef and b) either remove the MSI-X
code entirely or switch it to the proper pci_alloc_irq_vectors API.
