This Series:
Layer 2, Layer 3 E-W and Layer 3 N-S (NO NAT) changes for vlan
backed distributed logical router.
This Patch:
a. Introduce per physical network chassic mac bindings in ovs.
For example:
ovn-chassis-mac-mappings="physnet1:aa:bb:cc:dd:ee:ff,physnet2:a1:b2:c3:d4:e5:f6"
b. Replace router port mac with a chassis specific mac,
read from a. above.
For example:
cookie=0x0, duration=67765.830s, table=65, n_packets=0, n_bytes=0,
idle_age=65534, hard_age=65534, priority=150,reg15=0x1,metadata=0x4,
dl_src=00:00:01:01:02:03 actions=mod_dl_src:aa:bb:cc:dd:ee:ff,
mod_vlan_vid:1000,output:16
