Petr Machata f6668eac22 mlxsw: spectrum_qdisc: Offload mirroring on RED qevent early_drop
The RED qevents early_drop and mark can be offloaded under the following
fairly strict conditions:

- At most one filter is configured at the qevent block
- The protocol is "any"
- The classifier is matchall
- The action is trap, sample, or mirror with the same conditions as
  with other SPAN offloads
- The hw_counters type is none

In this patchset, implement offload of mirror for early_drop qevent.
The ECN trigger is currently not implemented in the FW and therefore
the mark qevent is not supported.

The qevent notifications look exactly like regular block binding
notifications with a binder type that identifies them as qevents.
Therefore the details of processing this binding are fairly similar
to the matchall offload.

struct flow_block_offload.sch points at the qdisc in question. Use it to
figure out if the qdisc is offloaded at all and what TC it configures.
Bounce bindings on not-offloaded qdiscs.

Individual bindings are kept in a list so that several qevents can share
the same block and all binding points get configured as the configured
filters change.

Petr Machata f7a439cbf1 mlxsw: spectrum_flow: Promote binder-type dispatch to spectrum.c
Two RED qevents have been introduced recently. From the point of view of a
driver, qevents are simply blocks with unusual binder types. However they
need to be handled by different logic than ACL-like flows.

Thus rename mlxsw_sp_setup_tc_block() to mlxsw_sp_setup_tc_block_clsact()
and move the binder-type dispatch from there to spectrum.c into a new
function of the original name. The new dispatcher is easier to extend with
new binder types.

Petr Machata b50f60a0c4 mlxsw: spectrum_matchall: Publish matchall data structures
A following patch introduces offloading of filters attached to blocks bound
to the RED tail_drop qevent. The only classifier that mlxsw will permit in
this role is matchall. mlxsw currently offloads matchall filters used with
clsact qdisc. The data structures used for that offload will come handy for
the qevent offload as well. Publish them in spectrum.h.

Ido Schimmel 2bafb216e1 mlxsw: spectrum_span: Add APIs to enable / disable global mirroring triggers
While the binding of global mirroring triggers to a SPAN agent is
global, packets are only mirrored if they belong to a port and TC on
which the trigger was enabled. This allows, for example, to mirror
packets that were tail-dropped on a specific netdev.

Implement the operations that allow to enable / disable a global
mirroring trigger on a specific port and TC.

Ido Schimmel ab8c06b7b4 mlxsw: spectrum_span: Add support for global mirroring triggers
Global mirroring triggers are triggers that are only keyed by their
trigger, as opposed to per-port triggers, which are keyed by their
trigger and port.

Such triggers allow mirroring packets that were tail/early dropped or
ECN marked to a SPAN agent.

Implement the previously added trigger operations for these global
triggers. Since such triggers are only supported from Spectrum-2
onwards, have the Spectrum-1 operations return an error.

Ido Schimmel 08a3641f26 mlxsw: spectrum_span: Prepare for global mirroring triggers
Currently, a SPAN agent can only be bound to a per-port trigger where
the trigger is either an incoming packet (INGRESS) or an outgoing packet
(EGRESS) to / from the port.

The subsequent patch will introduce the concept of global mirroring
triggers. The binding / unbinding of global triggers is different than
that of per-port triggers. Such triggers also need to be enabled /
disabled on a per-{port, TC} basis and are only supported from
Spectrum-2 onwards.

Add trigger operations that allow us to abstract these differences. Only
implement the operations for per-port triggers. Next patch will
implement the operations for global triggers.

Petr Machata c40f4e50b6 net: sched: Pass qdisc reference in struct flow_block_offload
Previously, shared blocks were only relevant for the pseudo-qdiscs ingress
and clsact. Recently, a qevent facility was introduced, which allows to
bind blocks to well-defined slots of a qdisc instance. RED in particular
got two qevents: early_drop and mark. Drivers that wish to offload these
blocks will be sent the usual notification, and need to know which qdisc it
is related to.

To that end, extend flow_block_offload with a "sch" pointer, and initialize
as appropriate. This prompts changes in the indirect block facility, which
now tracks the scheduler in addition to the netdevice. Update signatures of
several functions similarly.

Alex Elder e3eea08e64 net: ipa: fix kerneldoc comments
This commit affects comments (and in one case, whitespace) only.

Throughout the IPA code, return statements are documented using
"@Return:", whereas they should use "Return:" instead.  Fix these
mistakes.

In function definitions, some parameters are missing their comment
to describe them.  And in structure definitions, some fields are
missing their comment to describe them.  Add these missing
descriptions.

Some arguments changed name and type along the way, but their
descriptions were not updated (an endpoint pointer is now used in
many places that previously used an endpoint ID).  Fix these
incorrect parameter descriptions.

In the description for the ipa_clock structure, one field had a
semicolon instead of a colon in its description.  Fix this.

Add a missing function description for ipa_gsi_endpoint_data_empty().

All of these issues were identified when building with "W=1".

Christophe JAILLET 6d905436a2 net: skge: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'skge_up()', GFP_KERNEL can be used because
some other memory allocations done a few lines below in 'skge_ring_alloc()'
already use this flag.

David S. Miller 2faf34ba50 Merge branch 'Fix-MTU-warnings-for-fec-mv886xxx-combo'
Andrew Lunn says:

====================
Fix MTU warnings for fec/mv886xxx combo

Since changing the MTU of dsa slave interfaces was implemented, the
fec/mv88e6xxx combo has been giving warnings:

[    2.275925] mv88e6085 0.2:00: nonfatal error -95 setting MTU on port 9
[    2.284306] eth1: mtu greater than device maximum
[    2.287759] fec 400d1000.ethernet eth1: error -22 setting MTU to include DSA overhead

This patchset adds support for changing the MTU on mv88e6xxx switches,
which do support jumbo frames. And it modifies the FEC driver to
support its true MTU range, which is larger than the default Ethernet
MTU.

Andrew Lunn 5919305351 net: fec: Set max MTU size to allow the MTU to be changed
The FEC allocates 2K buffers, but looses some of it due to
alignment. It can however support an MTU bigger than the default. This
is particularly interesting when used in combination with Ethernet
switches supporting DSA, which have extra headers. The DSA core will
try to increase the MTU to support these extra headers. If the max
size defaults to that of standard Ethernet we get a warning. By
setting the max to what the driver actually supports, we avoid this
warning.

Nikolay Aleksandrov 9433944368 net: bridge: notify on vlan tunnel changes done via the old api
If someone uses the old vlan API to configure tunnel mappings we'll only
generate the old-style full port notification. That would be a problem
if we are monitoring the new vlan notifications for changes. The patch
resolves the issue by adding vlan notifications to the old tunnel netlink
code. As usual we try to compress the notifications for as many vlans
in a range as possible, thus a vlan tunnel change is considered able
to enter the "current" vlan notification range if:
 1. vlan exists
 2. it has actually changed (curr_change == true)
 3. it passes all standard vlan notification range checks done by
    br_vlan_can_enter_range() such as option equality, id continuity etc

Note that vlan tunnel changes (add/del) are considered a part of vlan
options so only RTM_NEWVLAN notification is generated with the relevant
information inside.
