If you are fresh to using Linux for development, like me, you may find the below are useful.
Some versions of `VIVADO License Manager `, like 2017.1, requires the NIC to be named like 'eth0' to be recognized to get licensed.
However, in latest stable version of Linux, like Ubuntu 16.04 LTS, the style like 'enp3s0' is used by default.
So we may want to change our NIC name back to 'eth{$}' style to get licensed.
Here is how I did:
1. [Ctrl+Alt+T] to open an terminal and type `ifconfig` to get your NIC information. Find your `HWaddr` info, a.k.a mac address, in the output.
For instance, a output like:
`
enp3s0 Link encap:Ethernet HWaddr 70:8b:11:11:11:11
inet addr:192.168.10.27 Bcast:192.168.10.255 Mask:255.255.255.0
`
Shows the `enp3s0` NIC 's mac address is `70:8b:11:11:11:11`
2. in the terminal, `sudo gedit /etc/udev/rules.d/70-persistent-net.rules` to create and open a new configuration, then add `SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="70:8b:11:11:11:11", NAME="eth0"` as its first(and only) line.
Do change `70:8b:11:11:11:11` to your own mac address.
Then reboot, and `ifconfig` to verify the NIC is changed
Tested on Ubuntu 16.04 LTS 64bit with VIVADO License Manager 2017.1
