They show up in `pciconf -lv` in the ppt devclass. However, most of the device configuration appears= to be invalid (see pciconf output below). In particular, the hdr=3D0x7f means `ppt_probe()` will return ENXIO for the device instead of BUS_PROBE_WILDCAR= D, preventing the device from being passed through to a bhyve VM. I naively tried modifying the vmm driver to bypass the cfg.hdrtype check, w= hich allowed me to pass the device through to a VM, but the kernel in the VM then failed to recognize the VF as anything. It is not present in `pciconf -l` inside the VM and I see no messages about it in the VM console. dev.t4nex.0.firmware_version: 1.19.1.0 ppt0@pci0:1:1:0: class=3D0xffffff card=3D0x00000000 chip=3D0x4801142= 5 rev=3D0xff hdr=3D0x7f vendor =3D 'Chelsio Communications Inc' device =3D 'T420-CR Unified Wire Ethernet Controller [VF]' --=20 You are receiving this mail because: You are the assignee for the bug.=
