There have been many people complaining about the inconsistent
behaviors of IPv4 and IPv6 devconf when creating new network
namespaces. Currently, for IPv4, we inherit all current settings

To me this feature makes more sense as a debugf-fs option.

Similar to u32 filter, it is useful to know how many times
we reach each basic filter and how many times we pass the
ematch attached to it.
Sample output:
filter protocol arp pref 49152 basic chain 0
filter protocol arp pref 49152 basic chain 0 handle 0x1 (rule hit 3 success 3)

On multiqueue network devices, RPS maps are configured independently
for each receive queue through /sys/class/net/$DEV/queues/rx-*.
On virtio-net currently all packets use the map from rx-0, because the
real rx queue is not known at time of map lookup by get_rps_cpu.

Count the number of times hooks were executed in the cgroup
local storage to make sure they trigger.

Currently, we have BPF_CGROUP_INET_SOCK_CREATE hook that triggers on
socket creation and there is no way to know when the socket is being
closed. Add new set of hooks BPF_CGROUP_INET{4,6}_SOCK_RELEASE
that trigger when the socket is closed.
Initial intended usecase is to cleanup statistics after P
These hooks mirror existing BPF_CGROUP_INET{4,6}_SOCK hooks (which
trigger upon socket creation), but trigger when the socket is closed.
