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.

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.

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.

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.

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".

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.
====================

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.

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.

were some improvements around __builtin_constant_p in that release. In
reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume
that we have a working compiler.

Commit 0c3d79bce4 ("tcp: reduce SYN-ACK
retrans for TCP_DEFER_ACCEPT") introduces syn_ack_recalc() which decides
if a minisock is held and a SYN+ACK is retransmitted or not.
If rskq_defer_accept is not zero in syn_ack_recalc(), max_retries always
has the same value because max_retries is overwritten by rskq_defer_accept
in reqsk_timer_handler().
This commit adds three changes:
- remove redundant non-zero check for rskq_defer_accept in
reqsk_timer_handler().
- remove max_retries from the arguments of syn_ack_recalc() and use
rskq_defer_accept instead.
- rename thresh to max_syn_ack_retries for readability.

mlxsw: Various fixes
Fix two issues found by syzkaller.
Patch #1 removes inappropriate usage of WARN_ON() following memory
allocation failure. Constantly triggered when syzkaller injects faults.
Patch #2 fixes a use-after-free that can be triggered by 'devlink dev
info' following a failed devlink reload.
