If I understand the bug report correctly, you are actually proposing
to enhance the ovs-docker script to also support setting the default
gateway. Am I Correct? If so, would you mind sending a patch to
d...@openvswitch.org using 'git format-patch' and 'git send-email'? If
you prefer that I do it instead, let me know.
Thanks,
Guru
