====================
net/smc: implement SMCv2.1 virtual ISM device support

The fourth edition of SMCv2 adds the SMC version 2.1 feature updates for
SMC-Dv2 with virtual ISM. Virtual ISM are created and supported mainly by
OS or hypervisor software, comparable to IBM ISM which is based on platform
firmware or hardware.

With the introduction of virtual ISM, SMCv2.1 makes some updates:

- Introduce feature bitmask to indicate supplemental features.
- Reserve a range of CHIDs for virtual ISM.
- Support extended GIDs (128 bits) in CLC handshake.

So this patch set aims to implement these updates in Linux kernel. And it
acts as the first part of SMC-D virtual ISM extension & loopback-ism [1].

v8->v7:
- Patch #7: v7 mistakenly changed the type of gid_ext in
  smc_clc_msg_accept_confirm to u64 instead of __be64 as previous versions
  when fixing the rebase conflicts. So fix this mistake.

v7->v6:
Link: https://lore.kernel.org/netdev/20231219084536.8158-1-guwen@linux.alibaba.com/
- Collect the Reviewed-by tag in v6;
- Patch #3: redefine the struct smc_clc_msg_accept_confirm;
- Patch #7: Because that the Patch #3 already adds '__packed' to
  smc_clc_msg_accept_confirm, so Patch #7 doesn't need to do the same thing.
  But this is a minor change, so I kept the 'Reviewed-by' tag.

Other changes in previous versions but not yet acked:
- Patch #1: Some minor changes in subject and fix the format issue
  (length exceeds 80 columns) compared to v3.
- Patch #5: removes useless ini->feature_mask assignment in __smc_connect()
  and smc_listen_v2_check() compared to v4.
- Patch #8: new added, compared to v3.

v6->v5:

- Add 'Reviewed-by' label given in the previous versions:
  * Patch #4, #6, #9, #10 have nothing changed since v3;
- Patch #2:
  * fix the format issue (Alignment should match open parenthesis) compared to v5;
  * remove useless clc->hdr.length assignment in smcr_clc_prep_confirm_accept()
    compared to v5;
- Patch #3: new added compared to v5.
- Patch #7: some minor changes like aclc_v2->aclc or clc_v2->clc compared to v5
  due to the introduction of Patch #3. Since there were no major changes, I kept
  the 'Reviewed-by' label.

  entries in CLC proposal and using SMC_MAX_V2_ISM_DEVS to indicate the
  max devices to propose;
- Patch #6: use i and i+1 in smc_find_ism_v2_device_serv();
- Patch #2: replace the large if-else block in smc_clc_send_confirm_accept()

Wen Gu b3bf76024f net/smc: manage system EID in SMC stack instead of ISM driver
The System EID (SEID) is an internal EID that is used by the SMCv2
software stack that has a predefined and constant value representing
the s390 physical machine that the OS is executing on. So it should
be managed by SMC stack instead of ISM driver and be consistent for
all ISMv2 device (including virtual ISM devices) on s390 architecture.

Wen Gu c6b8b8eb49 net/smc: disable SEID on non-s390 archs where virtual ISM may be used
The system EID (SEID) is an internal EID used by SMC-D to represent the
s390 physical machine that OS is executing on. On s390 architecture, it
predefined by fixed string and part of cpuid and is enabled regardless
of whether underlay device is virtual ISM or platform firmware ISM.

However on non-s390 architectures where SMC-D can be used with virtual
ISM devices, there is no similar information to identify physical
machines, especially in virtualization scenarios. So in such cases, SEID
is forcibly disabled and the user-defined UEID will be used to represent
the communicable space.

Marek Behún e9301af385 net: sfp: fix PHY discovery for FS SFP-10G-T module
Commit 2f3ce7a56c ("net: sfp: rework the RollBall PHY waiting code")
changed the long wait before accessing RollBall / FS modules into
probing for PHY every 1 second, and trying 25 times.

Wei Lei reports that this does not work correctly on FS modules: when
initializing, they may report values different from 0xffff in PHY ID
registers for some MMDs, causing get_phy_c45_ids() to find some bogus
MMD.

Fix this by adding the module_t_wait member back, and setting it to 4
seconds for FS modules.

Ioana Ciornei 71150d9447 dpaa2-switch: cleanup the egress flood of an unused FDB
In case a DPAA2 switch interface joins a bridge, the FDB used on the
port will be changed to the one associated with the bridge. What this
means exactly is that any VLAN installed on the port will need to be
removed and then installed back so that it points to the new FDB.

Once this is done, the previous FDB will become unused (no VLAN to
point to it). Even though no traffic will reach this FDB, it's best to
just cleanup the state of the FDB by zeroing its egress flood domain.

Ioana Ciornei f6da276479 dpaa2-switch: do not clear any interrupts automatically
The DPSW object has multiple event sources multiplexed over the same
IRQ. The driver has the capability to configure only some of these
events to trigger the IRQ.

The dpsw_get_irq_status() can clear events automatically based on the
value stored in the 'status' variable passed to it. We don't want that
to happen because we could get into a situation when we are clearing
more events than we actually handled.

Just resort to manually clearing the events that we handled. Also, since
status is not used on the out path we remove its initialization to zero.

This change does not have a user-visible effect because the dpaa2-switch
driver enables and handles all the DPSW events which exist at the
moment.

Ioana Ciornei 77c42a3b0a dpaa2-switch: add ENDPOINT_CHANGED to the irq_mask
Commit 84cba72956 ("dpaa2-switch: integrate the MAC endpoint support")
added support for MAC endpoints in the dpaa2-switch driver but omitted
to add the ENDPOINT_CHANGED irq to the list of interrupt sources. Fix
this by extending the list of events which can raise an interrupt by
extending the mask passed to the dpsw_set_irq_mask() firmware API.

There is no user visible impact even without this patch since whenever a
switch interface is connected/disconnected from an endpoint both events
are set (LINK_CHANGED and ENDPOINT_CHANGED) and, luckily, the
LINK_CHANGED event could actually raise the interrupt and thus get the
MAC/PHY SW configuration started.

Even with this, it's better to just not rely on undocumented firmware
behavior which can change.

Grygorii Strashko bc8d62e16e net: ethernet: ti: am65-cpsw: add mqprio qdisc offload in channel mode
This patch adds MQPRIO Qdisc offload in full 'channel' mode which allows
not only setting up pri:tc mapping, but also configuring TX shapers
(rate-limiting) on external port FIFOs.

The MQPRIO Qdisc offload is expected to work with or without VLAN/priority
tagged packets.

The CPSW external Port FIFO has 8 Priority queues. The rate-limit can be
set for each of these priority queues. Which Priority queue a packet is
assigned to depends on PN_REG_TX_PRI_MAP register which maps header
priority to switch priority.

The header priority of a packet is assigned via the RX_PRI_MAP_REG which
maps packet priority to header priority.

The packet priority is either the VLAN priority (for VLAN tagged packets)
or the thread/channel offset.

For simplicity, we assign the same priority queue to all queues of a
Traffic Class so it can be rate-limited correctly.

Configuration example:
 ethtool -L eth1 tx 5
 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off

 tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \
 map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \
 queues 1@0 1@1 1@2 hw 1 mode channel \
 shaper bw_rlimit min_rate 0 100mbit 200mbit max_rate 0 101mbit 202mbit

 tc qdisc replace dev eth2 handle 100: parent root mqprio num_tc 1 \
 map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 1@0 hw 1

 ip link add link eth1 name eth1.100 type vlan id 100
 ip link set eth1.100 type vlan egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7

In the above example two ports share the same TX CPPI queue 0 for low
priority traffic. 3 traffic classes are defined for eth1 and mapped to:
TC0 - low priority, TX CPPI queue 0 -> ext Port 1 fifo0, no rate limit
TC1 - prio 2, TX CPPI queue 1 -> ext Port 1 fifo1, CIR=100Mbit/s, EIR=1Mbit/s
TC2 - prio 3, TX CPPI queue 2 -> ext Port 1 fifo2, CIR=200Mbit/s, EIR=2Mbit/s

Roger Quadros d0f9535b31 net: ethernet: am65-cpsw: Rename TI_AM65_CPSW_TAS to TI_AM65_CPSW_QOS
We will use this Kconfig option to not only enable TAS/EST offload
but also other QoS features like Multiqueue priority descriptors
and MAC-Merge/Frame Preemption. TI_AM65_CPSW_QOS seems a more
appropriate Kconfig option name than TI_AM65_CPSW_TAS.

Vladimir Oltean 2491d66ae6 selftests: forwarding: ethtool_mm: support devices with higher rx-min-frag-size
Some devices have errata due to which they cannot report ETH_ZLEN (60)
in the rx-min-frag-size. This was foreseen of course, and lldpad has
logic that when we request it to advertise addFragSize 0, it will round
it up to the lowest value that is _actually_ supported by the hardware.

The problem is that the selftest expects lldpad to report back to us the
same value as we requested.

Make the selftest smarter by figuring out on its own what is a
reasonable value to expect.

Hangbin Liu 9d0b4ad82d kselftest/runner.sh: add netns support
Add a variable RUN_IN_NETNS if the user wants to run all the selected tests
in namespace in parallel. With this, we can save a lot of testing time.

Note that some tests may not fit to run in namespace, e.g.
net/drop_monitor_tests.sh, as the dwdump needs to be run in init ns.

I also added another parameter -p to make all the logs reported separately
instead of mixing them in the stdout or output.log.

Nit: the NUM in run_one is not used, rename it to test_num.

Dmitry Safonov 826eb9bcc1 selftest/tcp-ao: Rectify out-of-tree build
Trivial fix for out-of-tree build that I wasn't testing previously:

1. Create a directory for library object files, fixes:
> gcc lib/kconfig.c -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -I ../../../../../usr/include/ -iquote /tmp/kselftest/kselftest/net/tcp_ao/lib -I ../../../../include/  -o /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o -c
> Assembler messages:
> Fatal error: can't create /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o: No such file or directory
> make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1

2. Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes:
> In file included from lib/kconfig.c:6:
> lib/aolib.h:320:45: warning: ‘struct tcp_ao_add’ declared inside parameter list will not be visible outside of this definition or declaration
>   320 | extern int test_prepare_key_sockaddr(struct tcp_ao_add *ao, const char *alg,
>       |                                             ^~~~~~~~~~
...

3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore
   since commit f2745dc0ba ("selftests: stop using KSFT_KHDR_INSTALL")

4. Also, while at here, drop .DEFAULT_GOAL definition: that has a
   self-explaining comment, that was valid when I made these selftests
   compile on local v4.19 kernel, but not needed since
   commit 8ce72dc325 ("selftests: fix headers_install circular dependency")
