Diable NIC tunable not working

I have a NIC which I cannot disable with a tunable and I am not sure why. Works no issue with Broadcom or Intel ports.

ajaxnas02% ifconfig ue0
ue0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether be:3a:f2:b6:05:9f
nd6 options=9<PERFORMNUD,IFDISABLED>

What is this NIC anyway? It’s not my IPMI because that has a cable in and has an IP assigned to it.

Server board:
Supermicro X12SSL-i latest firmware updates.

I would assume to be the one managing the two Gigabit Ethernet LAN Ports, which according to Supermicro is a Broadcom BCM5720.

Thanks for the reply… This dual-nic is disabled in BIOS because they run too hot for my liking. I got a good price on the board and wanted the internal SATA controllers. These guys are known bge0 and bge1.

They do not show up in ifconfig.

Digging a little deeper in dmesg discovered RNDIS interface which is activated with the if_urndis driver. Further reading can be had here on this interface.

I have tried a post-init kldunload but it keeps restarting itself. Don’t want to mess with boot loader at cli so will be marked solved for now since I know the details on what & why.
