I just started using an ASRock Rack X470D4U2-2T:

<https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U2-2T#Specifications>
It sports an X550 dual 10G ethernet controller:
# pciconf -lv
ix0@pci0:1:0:0: class=0x020000 card=0x15631849 chip=0x15638086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = 'Ethernet Controller 10G X550T'
class = network
subclass = ethernet
ix1@pci0:1:0:1: class=0x020000 card=0x15631849 chip=0x15638086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = 'Ethernet Controller 10G X550T'
class = network
subclass = ethernet
It should support SR-IOV:
# ls -l /dev/iov
total 0
crw------- 1 root wheel 0x32 Jun 20 23:04 ix0
crw------- 1 root wheel 0x33 Jun 20 23:04 ix1
# iovctl -S -d ix1
The following configuration parameters may be configured on the PF:
num_vfs : uint16_t (required)
device : string (required)
The following configuration parameters may be configured on a VF:
passthrough : bool (default = false)
mac-addr : unicast-mac (optional)
mac-anti-spoof : bool (default = true)
allow-set-mac : bool (default = false)
allow-promisc : bool (default = false)
If I try to create a number of virtual devices, things don't seem to work out:
# cat /etc/iovctl-ix1.conf
PF {
device: "ix1";
num_vfs: 8;
}
DEFAULT {
passthrough: true;
}
VF-0 {
passthrough: false;
}
# iovctl -C -f /etc/iovctl-ix1.conf
# dmesg
...

I haven't tried the passthrough devices yet, but I am interested in having at
least one virtual device available in the host for use with a VIMAGE jail.

Should this be working? It seems some months ago it was necessary to compile
the Intel driver instead of the in-tree one. I would have assumed that it would
have been integrated by now.
