Subject: cfm: Add test for fault_override
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Fovs.git;a=commitdiff_plain;h=45ebaaf58c8dd017b5ba6a1ea18b77b8760a41e8

cfm: Add test for fault_override

This patch adds tests for the cfm fault_override feature which can be
set through "ovs-appctl cfm/set-fault <port> <value>". It brings up two
ports with CFM, sets a fault, then checks that the fault status has
propagated correctly to the CFM module and the database. Finally, it
sets the fault override behaviour to normal and checks that the fault
has gone away.
