We want to add reference counting for FDB entries in cross-chip
topologies, and in order for that to have any chance of working and not
be unbalanced (leading to entries which are never deleted), we need to
ensure that higher layers are sane, because if they aren't, it's garbage
in, garbage out.
For example, if we add a bridge FDB entry twice, the bridge properly
errors out:
$ bridge fdb add dev swp0 00:01:02:03:04:07 master static
$ bridge fdb add dev swp0 00:01:02:03:04:07 master static
RTNETLINK answers: File exists
However, the same thing cannot be said about the bridge bypass
operations:
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ echo $?
0
But one 'bridge fdb del' is enough to remove the entry, no matter how
many times it was added.
The bridge bypass operations are impossible to maintain in these
circumstances and lack of support for reference counting the cross-chip
notifiers is holding us back from making further progress, so just drop
support for them. The only way left for users to install static bridge
FDB entries is the proper one, using the "master static" flags.
With this change, rtnl_fdb_add() falls back to calling
ndo_dflt_fdb_add() which uses the duplicate-exclusive variant of
dev_uc_add(): dev_uc_add_excl(). Because DSA does not (yet) declare
IFF_UNICAST_FLT, this results in us going to promiscuous mode:
$ bridge fdb add dev swp0 00:01:02:03:04:05
[ 28.206743] device swp0 entered promiscuous mode
$ bridge fdb add dev swp0 00:01:02:03:04:05
RTNETLINK answers: File exists
So even if it does not completely fail, there is at least some indication
that it is behaving differently from before, and closer to user space
expectations, I would argue (the lack of a "local|static" specifier
defaults to "local", or "host-only", so dev_uc_add() is a reasonable
default implementation). If the generic implementation of .ndo_fdb_add
provided by Vlad Yasevich is a proof of anything, it only proves that
the implementation provided by DSA was always wrong, by not looking at
"ndm->ndm_state & NUD_NOARP" (the "static" flag which means that the FDB
entry points outwards) and "ndm->ndm_state & NUD_PERMANENT" (the "local"
flag which means that the FDB entry points towards the host). It all
used to mean the same thing to DSA.
Update the documentation so that the users are not confused about what's
going on.

Some really really weird switches just couldn't decide whether to use a
normal or a tail tagger, so they just did both.
This creates problems for DSA, because we only have the concept of an
'overhead' which can be applied to the headroom or to the tailroom of
the skb (like for example during the central TX reallocation procedure),
depending on the value of bool tail_tag, but not to both.
We need to generalize DSA to cater for these odd switches by
transforming the 'overhead / tail_tag' pair into 'needed_headroom /
needed_tailroom'.
The DSA master's MTU is increased to account for both.
The flow dissector code is modified such that it only calls the DSA
adjustment callback if the tagger has a non-zero header length.
Taggers are trivially modified to declare either needed_headroom or
needed_tailroom, based on the tail_tag value that they currently
declare.

"make htmldocs" complains:

configuration.rst:212: WARNING: duplicate label networking/dsa/configuration:bridge, other instance in (...)

And for good reason, because the "single port", "bridge" and "gateway"
use cases are replicated twice, once for normal taggers and twice for
DSA_TAG_PROTO_NONE. So when trying to reference these sections via a
hyperlink such as:
https://www.kernel.org/doc/html/latest/networking/dsa/configuration.html#single-port
it will always reference the first occurrence, and never the second one.
This change makes the "single port", "bridge" and "gateway"

"Configuration showcases" subsection.

On one hand, the link is dead and therefore useless.
On the other hand, there are always more drivers to port, but at this
stage, DSA does not need to affirm itself as the driver model to use for
Ethernet-connected switches (since we already have 15 tagging protocols
supported and probably more switch families from various vendors), so
there is nothing actionable to do.

DSA wants the master interface to be open before the user port is due to
historical reasons. The promiscuity of interfaces that are down used to
have issues, as referenced Lennert Buytenhek in commit df02c6ff2e39
("dsa: fix master interface allmulti/promisc handling").
The bugfix mentioned there, commit b6c40d68ff64 ("net: only invoke
dev->change_rx_flags when device is UP"), was basically a "don't do
that" approach to working around the promiscuity while down issue.
Further work done by Vlad Yasevich in commit d2615bf45069 ("net: core:
Always propagate flag changes to interfaces") has resolved the
underlying issue, and it is strictly up to the DSA and 8021q drivers
now, it is no longer mandated by the networking core that the master
interface must be up when changing its promiscuity.
From DSA's point of view, deciding to error out in dsa_slave_open
because the master isn't up is
(a) a bad user experience and
(b) knocking at an open door.
Even if there still was an issue with promiscuity while down, DSA could
still just open the master and avoid it.
Doing it this way has the additional benefit that user space can now
remove DSA-specific workarounds, like systemd-networkd with BindCarrier:
https://github.com/systemd/systemd/issues/7478
And we can finally remove one of the 2 bullets in the "Common pitfalls
using DSA setups" chapter.

Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.
No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g
However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.
In the meantime, also fix the following checks from checkpatch.pl to
make it happy with this patch:
CHECK: Comparison to NULL could be written "!ops"
#403: FILE: net/dsa/dsa.c:470:
+ if (ops == NULL) {
CHECK: Comparison to NULL could be written "ds->ops->get_strings"
#773: FILE: net/dsa/slave.c:697:
+ if (ds->ops->get_strings != NULL)
CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats"
#824: FILE: net/dsa/slave.c:785:
+ if (ds->ops->get_ethtool_stats != NULL)
CHECK: Comparison to NULL could be written "ds->ops->get_sset_count"
#835: FILE: net/dsa/slave.c:798:
+ if (ds->ops->get_sset_count != NULL)
total: 0 errors, 0 warnings, 4 checks, 784 lines checked

The DSA layer doesn't care about the return code of the port_stp_update
routine, so make it void in the layer and the DSA drivers.
Replace the useless dsa_slave_stp_update function with a
dsa_slave_stp_state function used to reply to the switchdev
SWITCHDEV_ATTR_ID_PORT_STP_STATE attribute.
In the meantime, rename port_stp_update to port_stp_state_set to
explicit the state change.
