In the new ENA-based instances like c6gn, the vector table moved to a new PCIe bar - BAR1. Previously it was always located on the BAR0, so the resources were already allocated together with the registers. As the FreeBSD isn't doing any resource allocation behind the scenes, the driver is responsible to allocate them explicitly, before other parts of the OS (like the PCI code allocating MSIx) will be able to access them. To determine dynamically BAR on which the MSIx vector table is present the pci_msix_table_bar() is being used and the new BAR is allocated if needed.
