From: Arnd Bergmann <arnd@arndb.de>
When VIRTIO_PCI_LIB is not built-in but the alibaba driver is, the kernel runs into a link error:
x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_features': eni_vdpa.c:(.text+0x23f): undefined reference to `vp_legacy_set_features' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_state': eni_vdpa.c:(.text+0x2fe): undefined reference to `vp_legacy_get_queue_enable' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_address': eni_vdpa.c:(.text+0x376): undefined reference to `vp_legacy_set_queue_address' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_ready': eni_vdpa.c:(.text+0x3b4): undefined reference to `vp_legacy_set_queue_address' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_free_irq': eni_vdpa.c:(.text+0x460): undefined reference to `vp_legacy_queue_vector' x86_64-linux-ld: eni_vdpa.c:(.text+0x4b7): undefined reference to `vp_legacy_config_vector' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_reset':
Selecting VIRTIO_PCI_LIB_LEGACY is not sufficient here since that is only part of the VIRTIO_PCI_LIB support.
