Title:
DVR: Fix dvr mac address format to be backward compatible with non
native openflow interface
Status in neutron:
Fix Released
Bug description:
DVR MAC address is configured on the server for every node that is
configured to run in one of the dvr agent modes ( dvr,dvr_snat and
dvr_no_external).
The DVR MAC addresses are stored in the 'AA-BB-CC-DD-EE-FF' format.
When the agent tries to configure the DVR MAC addresses into the
openflow rules using the native interface drivers, they are ok.
But when used with the non native interface drivers this throws an
error as shown below.
Unable to execute ['ovs-ofctl', 'add-flows', 'br-vlan1078', '-'].
Exception: Exit code: 1; Stdin:
hard_timeout=0,idle_timeout=0,priority=2,table=3,cookie=12002607947458125225,dl_src=FA-16
-3F-AA-78-20,actions=output:2; Stdout: ; Stderr: ovs-ofctl: -:1: FA-16
-3F-AA-78-20: invalid Ethernet address.
This is also seen in the Master branch.
So to provide backward compatibility, we need to add a patch to change the
format of the MAC before it is handed over to the openflow interface driver.
