Hi, OVS developers,
I am studying the hashing functions in OVS and find these two
implementations: hmap and cmap. I understand that cmap is the improved
cuckoo hashing and cmap supports multiple-reader and single writer. My
questions are:
1. What does hmap stand for? hash map?
2. hmap looks much

Hi,

The problem I have is that although OVS is allowed to use all available CPUs:
$ ovs-vsctl --no-wait get Open_vSwitch . other_config:pmd-cp
