14:21:05 <nikolam> using  /usr/lib/pci/pcieadm show-devs -o vendor,device,subvid,subsys,subvendor,subsystem 
14:21:18 <nikolam> i see: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller 10ec 8168 Realtek Semiconductor Co., Ltd. TP-Link TG-3468 v4.0 Gigabit PCI Express Network Adapter
14:22:28 <nikolam> as rge "pciex10ec,8161" is in /etc/driver_aliases
14:23:41 <nikolam> But external_nic= has it's MAC address I see under dladm show-phys -m 
14:23:53 <nikolam> But it is not in use.. 
14:28:25 <nikolam> So I gues it is not only the driver_aliases
