Casey Leedom 7dcf688d4c PCI/cxgb4: Extend T3 PCI quirk to T4+ devices ... We've run into a problem where our device is attached to a Virtual Machine and the use of the new pci_set_vpd_size() API doesn't help. The VM kernel has been informed that the accesses are okay, but all of the actual VPD Capability Accesses are trapped down into the KVM Hypervisor where it goes ahead and imposes the silent denials. The right idea is to follow the kernel.org commit 1c7de2b4ff ("PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)") which Alexey Kardashevskiy authored to establish a PCI Quirk for our T3-based adapters. This commit extends that PCI Quirk to cover Chelsio T4 devices and later. The advantage of this approach is that the VPD Size gets set early in the Base OS/Hypervisor Boot and doesn't require that the cxgb4 driver even be available in the Base OS/Hypervisor. Thus PF4 can be exported to a Virtual Machine and everything should work.
