The system came up with a primary interface ixv0. Per pciconf - ixv0@pci0:0:3:0: class=3D0x020000 card=3D0x00000000 = chip=3D0x10ed8086 rev=3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D '82599 Ethernet Controller Virtual Function' class =3D network subclass =3D ethernet I attached another network interface while the system is up. But, it = does not show up in the pciconf -l (or ifconfig) output. It appears on = reboot though. Is there any way to force the new interface to attach dynamically (AWS calls this 'hot attach') on FreeBSD? I think an action of probing the PCI device tree is needed. But, did not find any command to = do it. BTW, this works on Linux. It is not clear to me if the Linux AMI has some additional scripts to do this. Thanks, -Krishna=
