This reverts commit c645550bb249 ("odp-util: Always report
ODP_FIT_TOO_LITTLE for IGMP.")
Always forcing a slow path action can result in some over-broad
flows which swallow all traffic and force them to userspace, as reported

Without this patch "ovs-appctl dpctl/ct-bkts" produces the following

The purpose of this commit is to split the current way of storing the
conn nodes. Before this patch the nodes were stored into a single cmap
using ct->lock to avoid concurrent write access.
With this commit a single connection can be stored into one or two (at
most) CONNTRACK_BUCKETS available
From: Peng He
Currently, when doing NAT, the userspace conntrack will use an extra
conn for the two directions in a flow. However, each conn has actually
the two keys for both orig and rev directions. This patch introduces a
key_node[CT_DIR_MAX] member in the conn which consists of key and a
From: Gaetan Rivet
Multiple lookups are done to stored timeout policies, each time blocking
the global 'ct_lock'. This is usually not necessary and it should be
acceptable to get policy updates slightly delayed (by one RCU sync
at most). Using a CMAP reduces multiple lock taking and releasing in
From: Gaetan Rivet
Change the data structure from hmap to cmap for zone limits.
As they are shared amongst multiple conntrack users, multiple
readers want to check the current zone limit state before progressing in
their processing. Using a CMAP allows doing lookups without taking the

This series aims to share the work done so far, and to start a
discussion of a slightly different approach in terms of the way we
handle the connections.
It's not considered ready as further work and extensive tests are
needed.
There are two main logical changes that the series tries to
