ethernet interfaces in libvirt currently do not support bandwidth setting.

Although this doesn't confuse git, it might confuse something else. Leaving it without '----' is ok.
Please review it and if it appears ok, please apply. thanks, Anirban Chakraborty
No need to have this in the commit message, it's kept in the log then.

In libvirt, we indent by spaces. This would be caught by running 'make syntax-check'. Anyway, running 'make syntax-check check' is a good practice to follow before formatting the patches.

Same here. We need to clear the bandwidth settings when shutting down the domain or unplugging the device. Looking forward to v2, Martin
