Placing nftables set support in an extra module is pointless:
1. nf_tables needs dynamic registeration interface for sake of one module
2. nft heavily relies on sets, e.g. even simple rule like
"nft ... tcp dport { 80, 443 }" will not work with _SETS=n.
IOW, either nftables isn't used or both nf_tables and nf_tables_set
modules are needed anyway.
With extra module:
307K net/netfilter/nf_tables.ko
79K net/netfilter/nf_tables_set.ko

Like vxlan and erspan opts, geneve opts should also be supported in
nft_tunnel. The difference is geneve RFC (draft-ietf-nvo3-geneve-14)
allows a geneve packet to carry multiple geneve opts. So with this
patch, nftables/libnftnl would do:
# nft add table ip filter
# nft add chain ip filter input { type filter hook input priority 0 \; }
# nft add tunnel filter geneve_02 { type geneve\; id 2\; \
ip saddr 192.168.1.1\; ip daddr 192.168.1.2\; \
sport 9000\; dport 9001\; dscp 1234\; ttl 64\; flags 1\; \
opts \"1:1:34567890,2:2:12121212,3:3:1212121234567890\"\; }
# nft list tunnels table filter
table ip filter {
tunnel geneve_02 {
id 2
ip saddr 192.168.1.1
ip daddr 192.168.1.2
sport 9000
dport 9001
tos 18
ttl 64
flags 1
geneve opts 1:1:34567890,2:2:12121212,3:3:1212121234567890
}
}

This is a snapshot of hardidletimer netfilter target.
This patch implements a hardidletimer Xtables target that can be
used to identify when interfaces have been idle for a certain period
of time.
Timers are identified by labels and are created when a rule is set
with a new label. The rules also take a timeout value (in seconds) as
an option. If more than one rule uses the same timer label, the timer
will be restarted whenever any of the rules get a hit.
One entry for each timer is created in sysfs. This attribute contains
the timer remaining for the timer to expire. The attributes are
located under the xt_idletimer class:
/sys/class/xt_idletimer/timers/<label>
When the timer expires, the target module sends a sysfs notification
to the userspace, which can then decide what to do (eg. disconnect to
save power)
Compared to IDLETIMER, HARDIDLETIMER can send notifications when
CPU is in suspend too, to notify the timer expiry.
v1->v2: Moved all functionality into IDLETIMER module to avoid
code duplication per comment from Florian.

This change moves the mptcp socket allocation from mptcp_accept() to
subflow_syn_recv_sock(), so that subflow->conn is now always set
for the non fallback scenario.
It allows cleaning up a bit mptcp_accept() reducing the additional
locking and will allow fourther cleanup in the next patch.

Being a non-physical port, the CPU port does not have an ocelot_port
structure, so the ocelot_port_writel call inside the
ocelot_port_set_maxlen() function would access data behind a NULL

This patch splits the MSCC driver into separate files, per
functionality, to improve readability and maintenance as the codebase
grew a lot. The MACsec code is moved to a dedicated mscc_macsec.c file,
the mscc.c file is renamed to mscc_main.c to keep the driver binary to
be named mscc and common definition are put into a new mscc.h header.
Most of the code was just moved around, except for a few exceptions:
- Header inclusions were reworked to only keep what's needed.
- Three helpers were created in the MACsec code, to avoid #ifdef's in
the main C file: vsc8584_macsec_init, vsc8584_handle_macsec_interrupt
and vsc8584_config_macsec_intr.
The patch should not introduce any functional modification.

The MSCC PHY driver is growing, with lots of space consuming features
(firmware support, full initialization, MACsec...). It's becoming hard
to read and navigate in its source code. This patch moves the MSCC
driver to its own directory, without modifying anything, as a
preparation for splitting up its features into dedicated files.

Extend RED testsuite to cover the new nodrop mode of RED-ECN. This test is
really similar to ECN test, diverging only in the last step, where UDP
traffic should go to backlog instead of being dropped. Thus extract a
common helper, ecn_test_common(), make do_ecn_test() into a relatively
simple wrapper, and add another one, do_ecn_nodrop_test().

RED ECN nodrop mode means that non-ECT traffic should not be early-dropped,
but enqueued normally instead. In Spectrum systems, this is achieved by
disabling CWTPM.ew (enable WRED) for a given traffic class.
So far CWTPM.ew was unconditionally enabled. Instead disable it when the
RED qdisc is in nodrop mode.

When the RED Qdisc is currently configured to enable ECN, the RED algorithm
is used to decide whether a certain SKB should be marked. If that SKB is
not ECN-capable, it is early-dropped.
It is also possible to keep all traffic in the queue, and just mark the
ECN-capable subset of it, as appropriate under the RED algorithm. Some
switches support this mode, and some installations make use of it.
To that end, add a new RED flag, TC_RED_NODROP. When the Qdisc is
configured with this flag, non-ECT traffic is enqueued instead of being
early-dropped.

The qdiscs RED, GRED, SFQ and CHOKE use different subsets of the same pool
of global RED flags. These are passed in tc_red_qopt.flags. However none of
these qdiscs validate the flag field, and just copy it over wholesale to
internal structures, and later dump it back. (An exception is GRED, which
does validate for VQs -- however not for the main setup.)
A broken userspace can therefore configure a qdisc with arbitrary
unsupported flags, and later expect to see the flags on qdisc dump. The
current ABI therefore allows storage of several bits of custom data to
qdisc instances of the types mentioned above. How many bits, depends on
which flags are meaningful for the qdisc in question. E.g. SFQ recognizes
flags ECN and HARDDROP, and the rest is not interpreted.
If SFQ ever needs to support ADAPTATIVE, it needs another way of doing it,
and at the same time it needs to retain the possibility to store 6 bits of
uninterpreted data. Likewise RED, which adds a new flag later in this
patchset.
To that end, this patch adds a new function, red_get_flags(), to split the
passed flags of RED-like qdiscs to flags and user bits, and
red_validate_flags() to validate the resulting configuration. It further
adds a new attribute, TCA_RED_FLAGS, to pass arbitrary flags.
