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.

Virtual ISM devices introduced in SMCv2.1 requires a 128 bit extended
GID vs. the existing ISM 64bit GID. So the 2nd 64 bit of extended GID
should be included in SMC-D linkgroup netlink attribute as well.

According to virtual ISM support feature defined by SMCv2.1, GIDs of
virtual ISM device are UUIDs defined by RFC4122, which are 128-bits
long. So some adaptation work is required. And note that the GIDs of
existing platform firmware ISM devices still remain 64-bits long.

The structs of CLC accept and confirm messages for SMCv1 and SMCv2 are
separately defined and often casted to each other in the code, which may
increase the risk of errors caused by future divergence of them. So
unify them into one struct for better maintainability.

Commit 2f3ce7a56c6e ("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.

encountering errors to reorganizing code to be easily extensible.
Changes in v3:
- 4/8: removed the fixes tag and moved it to the commit message
- 5/8: specified that there is no user-visible effect
- 6/8: removed the initialization of the err variable
Changes in v2:
- No changes to the actual diff, only rephrased some commit messages and
added more information.

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.

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.

Commit 84cba72956fd ("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.

Add driver support for viewing / changing the MAC Merge sublayer
parameters and seeing the verification state machine's current state
via ethtool.
As hardware does not support interrupt notification for verification
events we resort to polling on link up. On link up we try a couple of
times for verification success and if unsuccessful then give up.
The Frame Preemption feature is described in the Technical Reference
Manual [1] in section:
12.3.1.4.6.7 Intersperced Express Traffic (IET – P802.3br/D2.0)
Due to Silicon Errata i2208 [2] we set limit min IET fragment size to

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

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.

> 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 f2745dc0ba3d ("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 8ce72dc32578 ("selftests: fix headers_install circular dependency")
Fixes: cfbab37b3da0 ("selftests/net: Add TCP-AO library")

====================
tcp: Refactor bhash2 and remove sk_bind2_node.
This series refactors code around bhash2 and remove some bhash2-specific
fields; sock.sk_bind2_node, and inet_timewait_sock.tw_bind2_node.
patch 1 : optimise bind() for non-wildcard v4-mapped-v6 address
patch 2 - 4 : optimise bind() conflict tests
patch 5 - 12 : Link bhash2 to bhash and unlink sk from bhash2 to
remove sk_bind2_node
The patch 8 will trigger a false-positive error by checkpatch.
v2: resend of https://lore.kernel.org/netdev/20231213082029.35149-1-kuniyu@amazon.com/
* Rebase on latest net-next
* Patch 11
* Add change in inet_diag_dump_icsk() for recent bhash dump patch
v1: https://lore.kernel.org/netdev/20231023190255.39190-1-kuniyu@amazon.com/

Now all sockets including TIME_WAIT are linked to bhash2 using
sock_common.skc_bind_node.
We no longer use inet_bind2_bucket.deathrow, sock.sk_bind2_node,
and inet_timewait_sock.tw_bind2_node.

Now we can use sk_bind_node/tw_bind_node for bhash2, which means
we need not link TIME_WAIT sockets separately.
The dead code and sk_bind2_node will be removed in the next patch.

Now we do not use tb->owners and can unlink sockets from bhash.
sk_bind_node/tw_bind_node are available for bhash2 and will be
used in the following patch.

We use hlist_empty(&tb->owners) to check if the bhash bucket has a socket.
We can check the child bhash2 buckets instead.
For this to work, the bhash2 bucket must be freed before the bhash bucket.

Sockets in bhash are also linked to bhash2, but TIME_WAIT sockets
are linked separately in tb2->deathrow.
Let's replace tb->owners iteration in inet_csk_bind_conflict() with
two iterations over tb2->owners and tb2->deathrow.
This can be done safely under bhash's lock because socket insertion/
deletion in bhash2 happens with bhash's lock held.
Note that twsk_for_each_bound_bhash() will be removed later.

The following patch adds code in the !inet_use_bhash2_on_bind(sk)
case in inet_csk_bind_conflict().
To avoid adding nest and make the change cleaner, this patch
rearranges tests in inet_csk_bind_conflict().
