It is important to keep conjunction IDs consistent between runs to avoid
unnecessary OVS flows deletion and reinstallation. However, There are two
problems of the current lflow-cache based conjunction id peristent approach.
1) When n_conjs changes, the cached conj_id_ofs can overlap with other lflows.
2) When lflow-cache is not enabled, conjunction id is not consistent across
runs.
This series replace the lflow-cache based approach by a new way of conjunction
id generation which keeps the ids consistent regardless of the lflow-cache
enablement.
Han Zhou (3):
lflow-cache.h: Fix comment about lflow-cache.
lflow-cache: Remove conjunction id cache.
lflow: Consistent conjunction id generation.
