From 8788ac191a4e0689f0287695c181fe1a781b0d31 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] Support configuring Load Balancer hairpin source IP.
In case traffic that gets load balanced is DNAT-ed to a backend IP that
happens to be the source of the traffic then OVN performs an additional
SNAT to ensure that return traffic is directed through OVN.
Until now the load balancer VIP was chosen as SNAT IP. However, in
specific scenarios, the CMS may prefer a different IP, e.g., a single
cluster-wide IP. This commit adds support, through the newly added
Load_Balancer.option 'hairpin_snat_ip', to allow the CMS to explicitly
chose a SNAT IP.
Due to the fact that now traffic that was hairpinned might need to be
SNAT-ed to different IPs for different load balancers that share the
same VIP address value we need to also explicitly match on L4 protocol
and ports in the 'OFTABLE_CT_SNAT_FOR_VIP' table.
