[ovs-dev] [PATCH v1] ovs-ofctl: Fixed the "snoop" command of ovs-ofctl

[Ashish Varma]

In case where "use_names" is set (e.g. in an interactive session) to show
the port and table names when ovs-ofctl is run with snoop command,
ovs-ofctl would get stuck in an endless loop inside "table_iterator_next"
function's while loop checking for "while (ti->send_xid != recv_xid)".
This would happening because the "vconn" to "<bridge>.snoop" socket would
not respond to TABLE_FEATURES_REQUEST sent by ovs-ofctl.

This commit disables showing port or table names in the snoop command.
