Backport lots upstream changes, many of them fixes, for the mt7530 DSA driver. Some of them may or may not find they way into Linux 6.1 stable, some certainly won't because they are fixes for backported commits which aren't even present in Linux 6.1 upstream. Apart from adding new patches, also remove mutated patch 723-net-mt7531-ensure-all-MACs-are-powered-down-before-r.patch which should never have been added for Linux 6.1 -- it was applied already upstream but coincidentally would fuzzy-apply in the wrong place as well (for MT7530 instead of MT7531). While that didn't really hurt anyone it is just unneeded. The other deleted patch 795-mt7530-register-OF-node-for-internal-MDIO-bus.patch has been replaced by an equivalent commit with a more complete patch description by upstream maintainer Arınç Ünal. The remaining differences compared to the upstream driver are: * C22/C45 MDIO ops aren't split Upstream did that, backporting it would require making changes to *all* DSA drivers * 'slave' -> 'user', 'master' -> 'conduit' language change in DSA * support for selecting preferred CPU port on MT7531 Also this would require too many DSA framework changes potentially affecting other devices. If we ever really use Linux 6.1 in a release (I hope not) we can still reconsider to make the effort to backport that. In addition to some minor bug fixes and style improvements the switch should now behave more conformant when it comes to link-local frames, and we will again be able to cleanly pick patches from upstream. MAINTAIERS NOTE: Three patches are already part of Linux stable and should be removed with the next minor kernel version bump: 789-STABLE-01-net-dsa-mt7530-prevent-possible-incorrect-XTAL-frequ.patch 789-STABLE-02-net-dsa-mt7530-fix-link-local-frames-that-ingress-vl.patch 789-STABLE-03-net-dsa-mt7530-fix-handling-of-all-link-local-frames.patch Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH 36/48] net: dsa: mt7530: do not clear
|
||
config->supported_interfaces

MIME-Version: 1.0

||
There's no need to clear the config->supported_interfaces bitmap before
|
||
reporting the supported interfaces as all bits in the bitmap will already
|
||
be initialized to zero when the phylink_config structure is allocated. The
|
||
"config" pointer points to &dp->phylink_config, and "dp" is allocated by
|
||
dsa_port_touch() with kzalloc(), so all its fields are filled with zeroes.
|
||
|
||
There's no code that would change the bitmap beforehand. Remove it.
