* Internal OpenFlow rule representation for load and set-field
actions is now much more memory efficient. For a complex flow
table this can reduce rule memory consumption by 40%.
* Bundles are now much more memory efficient than in OVS 2.5.
Together with memory efficiency improvements in OpenFlow rule
representation, the peak OVS resident memory use during a
bundle commit for large complex set of flow mods can be only
25% of that in OVS 2.5 (4x lower).
