ULT-WIIQ USB 2,5G Ethernet Adapter, USB 3.0 + Synology 918+: works

[shwill]

Description of the problem

The config below works on my 918+. After attaching the USB, I saw messages on dmesg that I interpreted as "not working properly"):

[437172.770537] netif_napi_add() called with weight 256 on device eth%d

and I did not see the interface in the DSM UI. I logged for the interfaces with ip link and it appeared correctly as eth2. I then copied the config of eth0 (/etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-ovs_eth0) as their eth2 equivalent and adjusted the values in the configs accordingly in a I don't have any idea what I am doing-methodology. After restarting the network with /etc/rc.network restart the interface appeared in the UI and can be configured to my liking now.

Can't say anything about stability. Cloning six VMs from a template using terraform didn't become quicker, but that's more related to the disk setup on the 918 than anything, I guess.
