Subject: [PATCH] net: page_pool: use in_softirq() instead
We use BH context only for synchronization, so we don't care if it's
actually serving softirq or not.
As a side node, in case of threaded NAPI, in_serving_softirq() will
return false because it's in process context with BH off, making
page_pool_recycle_in_cache() unreachable.

From 82b318983c515f29b8b3a0dad9f6a5fe8a68a7f4 Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: Wed, 20 Oct 2021 20:49:49 +0300
Subject: [PATCH] net: dsa: introduce helpers for iterating through ports using
dp
Since the DSA conversion from the ds->ports array into the dst->ports
list, the DSA API has encouraged driver writers, as well as the core
itself, to write inefficient code.
Currently, code that wants to filter by a specific type of port when
iterating, like {!unused, user, cpu, dsa}, uses the dsa_is_*_port helper.
Under the hood, this uses dsa_to_port which iterates again through
dst->ports. But the driver iterates through the port list already, so
the complexity is quadratic for the typical case of a single-switch
tree.
This patch introduces some iteration helpers where the iterator is
already a struct dsa_port *dp, so that the other variant of the
filtering functions, dsa_port_is_{unused,user,cpu_dsa}, can be used
directly on the iterator. This eliminates the second lookup.
These functions can be used both by the core and by drivers.

From 7f54cc9772ced2d76ac11832f0ada43798443ac9 Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Mon, 3 Apr 2023 02:19:02 +0100
Subject: [PATCH 13/16] net: dsa: mt7530: split-off common parts from
mt7531_setup
MT7988 shares a significant part of the setup function with MT7531.
Split-off those parts into a shared function which is going to be used
also by mt7988_setup.
