Add selftests for bpf_skb_ancestor_cgroup_id helper.
test_skb_cgroup_id.sh prepares testing interface and adds tc qdisc and
filter for it using BPF object compiled from test_skb_cgroup_id_kern.c
program.
BPF program in test_skb_cgroup_id_kern.c gets ancestor cgroup id using
the new helper at diff
This patch set adds new BPF helper bpf_skb_ancestor_cgroup_id that returns
id of cgroup v2 that is ancestor of cgroup associated with the skb at the
ancestor_level.
The helper is useful to implement policies in TC based on cgroups that are

== Problem description ==
It's useful to be able to identify cgroup associated with skb in TC so
that a policy can be applied to this skb, and existing bpf_skb_cgroup_id
helper can help with this.
Though in real life cgroup hierarchy and hierarchy to apply a policy to
don't map 1:1.

to be NEXTHDF_FRAGMENT. This patch tries to derive the IP protocol

used in the follow-up patch. No runtime changes yet.
The new logic (fully implemented in the second patch) is as follows:
* Nodes in the rb-tree will now contain not single fragments, but lists
of consecutive fragments ("runs").
This patch changes the runtime behavior of IP defrag queue:
incoming in-order fragments are added to the end of the current
list/"run" of in-order fragments at the tail.
On some workloads, UDP stream performance is substantially improved:
RX: ./udp_stream -F 10 -T 2 -l 60
TX: ./udp_stream -c -H

Updated README.
Added config file that contains the minimum required features enabled to
run the tests currently present in the kernel.
This must be updated when new unittests are created and require their own
modules.

This helper obtains the active namespace from current and returns pid, tgid,
device and namespace id as seen from that namespace, allowing to instrument
a process inside a container.
Device is read from /proc/self/ns/pid, as in the future it's possible that
different pid_ns files may belong to diff
Background: cpumap moves the SKB allocation out of the driver code,
and instead allocate it on the remote CPU, and invokes the regular
kernel network stack with the newly allocated SKB.
The idea behind the XDP CPU redirect feature, is to use XDP as a
load-balancer step in-front of regular kernel n
From: Jesper Dangaard Brouer
This implement XDP CPU redirection load-balancing across available
CPUs, based on the hashing IP-pairs + L4-protocol. This equivalent to
xdp-cpu-redirect feature in Suricata, which is inspired by the
Suricata 'ippair' hashing code.
An important property is that the
Adjusted function call API to take an initval. This allow the API
user to set the initial value, as a seed. This could also be used for
inputting the previous hash.
