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.
