Code review comment for lp://qastaging/~doanac/lava-dispatcher/fm-android-support

Not sure what happened here but there are conflicts in the diff.

Also, I think the new version of get_default_nic_ip will fail with a NameError if _get_default_nic_ip_by_ifconfig fails. I recommend changing the 'pass' in:

15 logging.exception("_get_default_nic_ip_by_ifconfig failed")
16 pass

to "return None"
