Hi Folks,
I have an AWS instance (m4.large) running FreeBSD 11.0-STABLE-amd64-2017-04-20.
The system came up with a primary interface ixv0. Per pciconf -
ixv0@pci0:0:3:0: class=0x020000 card=0x00000000 chip=0x10ed8086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = '82599 Ethernet Controller Virtual Function'
class = network
subclass = 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
