From: Numan Siddique
This patch add a new column 'selection_fields' in Load_Balancer
table in NB DB. CMS can define a set of packet headers to use
while selecting a backend. If this column is set, OVN will add the
flow in group table with selection method as 'hash' with the set fields.
Otherwise it will use the default 'dp_hash' selection method.
If a load balancer is configured with the selection_fields as
selection_fields : [ip_dst, ip_src, tp_dst, tp_src]
then with this patch, the modified ct_lb action will look like
- ct_lb(backends=IP1:P1-IP2:P1, hash_fields="ip_dst,ip_src,tp_dst,tp_src");
And the OF flow will look like
- group_id=2,type=select,selection_method=hash,
fields(ip_src,ip_dst,tcp_src,tcp_dst),bucket=bucket_id:0,weight:100,actions=ct(....
