A link time bug that I had fixed before has come back now that
another sub-module was added to the enetc driver:

ERROR: modpost: "enetc_ierb_register_pf" [drivers/net/ethernet/freescale/enetc/fsl-enetc.ko] undefined!

The problem is that the enetc Makefile is not actually used for
the ierb module if that is the only built-in driver in there
and everything else is a loadable module.

Fix it by always entering the directory this time, regardless
of which symbols are configured. This should reliably fix the
problem and prevent it from coming back another time.

net: dsa: Allow default tag protocol to be overridden from DT

This is a continuation of the work started in this patch:
https://lore.kernel.org/netdev/20210323102326.3677940-1-tobias@waldekranz.com/

In addition to the mv88e6xxx support to dynamically change the
protocol, it is now possible to override the protocol from the device
tree. This means that when a board vendor finds an incompatibility,
they can specify a working protocol in the DT, and users will not have
to worry about it.

Some background information:

In a system using an NXP T1023 SoC connected to a 6390X switch, we
noticed that TO_CPU frames where not reaching the CPU. This only
happened on hardware port 8. Looking at the DSA master interface
(dpaa-ethernet) we could see that an Rx error counter was bumped at
the same rate. The logs indicated a parser error.

It just so happens that a TO_CPU coming in on device 0, port 8, will
result in the first two bytes of the DSA tag being one of:

00 40
00 44
00 46

My guess was that since these values looked like 802.3 length fields,
the controller's parser would signal an error if the frame length did
not match what was in the header.

This was later confirmed using two different workarounds provided by
Vladimir. Unfortunately these either bypass or ignore the hardware
parser and thus robs working combinations of the ability to do RSS and
other nifty things. It was therefore decided to go with the option of
a DT override.

v1 -> v2:
  - Fail if the device does not support changing protocols instead of
    falling back to the default. (Andrew)
  - Only call change_tag_protocol on CPU ports. (Andrew/Vladimir)
  - Only allow changing the protocol on chips that have at least
    "undocumented" level of support for EDSA. (Andrew).
  - List the supported protocols in the binding documentation. I opted
    for only listing the protocols that I have tested. As more people
    test their drivers, they can add them. (Rob)

v2 -> v3:
  - Rename "dsa,tag-protocol" -> "dsa-tag-protocol". (Rob)
  - Some cleanups to 4/5. (Vladimir)
  - Add a comment detailing how tree/driver agreement on the tag
    protocol is enforced. (Vladimir).

All devices are capable of using regular DSA tags. Support for
Ethertyped DSA tags sort into three categories:

1. No support. Older chips fall into this category.

2. Full support. Datasheet explicitly supports configuring the CPU
   port to receive FORWARDs with a DSA tag.

3. Undocumented support. Datasheet lists the configuration from
   category 2 as "reserved for future use", but does empirically
   behave like a category 2 device.

So, instead of listing the one true protocol that should be used by a
particular chip, specify the level of support for EDSA (support for
regular DSA is implicit on all chips). As before, we use EDSA for all
chips that fully supports it.

In upcoming changes, we will use this information to support
dynamically changing the tag protocol.

mlxsw: Refactor qdisc offload

Currently, mlxsw admits for offload a suitable root qdisc, and its
children. Thus up to two levels of hierarchy are offloaded. Often, this is
enough: one can configure TCs with RED and TCs with a shaper, and can even
see counters for each TC by looking at a qdisc at a sufficiently shallow
position.

While simple, the system has obvious shortcomings. It is not possible to
configure both RED and shaping on one TC. It is not possible to place a
PRIO below root TBF, which would then be offloaded as port shaper. FIFOs
are only offloaded at root or directly below, which is confusing to users,
because RED and TBF of course have their own FIFO.

This patchset is a step towards the end goal of allowing more comprehensive
qdisc tree offload and cleans up the qdisc offload code.

- Patches #1-#4 contain small cleanups.

- Up until now, since mlxsw offloaded only a very simple qdisc
  configurations, basically all bookkeeping was done using one container
  for the root qdisc, and 8 containers for its children. Patches #5, #6, #8
  and #9 gradually introduce a more dynamic structure, where parent-child
  relationships are tracked directly at qdiscs, instead of being implicit.

- This tree management assumes only one qdisc is created at a time. In FIFO
  handlers, this condition was enforced simply by asserting RTNL lock. But
  instead of furthering this RTNL dependence, patch #7 converts the whole
  qdisc offload logic to a per-port mutex.

- Patch #10 adds a selftest.

Refer to the child qdiscs through this pointer, instead of going through

num_classes, which holds number of given qdisc's children.

Also introduce a generic function for walking qdisc trees. Rewrite
mlxsw_sp_qdisc_find() and _find_by_handle() to use the generic walker.

When a qdisc is removed, it is necessary to update the backlog value at its
parent--unless the qdisc is at root position. RED, TBF and FIFO all do
that, each separately. Since all of them need to do this, just promote the
operation directly to mlxsw_sp_qdisc_destroy(), instead of deferring it to
individual destructors. Since FIFO dtor thus becomes trivial, remove it.

Add struct mlxsw_sp_qdisc.parent to point at the parent qdisc. This will be
handy later as deeper structures are offloaded. Use the parent qdisc to
find the chain of parents whose backlog value needs to be updated.
