Daniel Golle 4354b34f6f generic: 6.6: sync mt7530 DSA driver with upstream
Backport lots upstream changes, many of them fixes, for the mt7530 DSA
driver, similar to how it was done for Linux 6.1 in the previous commit.

The remaining differences compared to the upstream driver are only
the 'slave' -> 'user', 'master' -> 'conduit' language change in DSA
and the rename of 'struct ethtool_eee' to 'struct ethtool_keee' as
well as tree-wide replacement of ethtool_sprintf with ethtool_puts,
all of them do not have any functional impact.

Apart from 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.

Subject: [PATCH 12/30] net: dsa: mt7530: empty default case on
mt7530_setup_port5()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There're two code paths for setting up port 5:
mt7530_setup()
-> mt7530_setup_port5()
mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt7530_mac_config()
-> mt7530_setup_port5()
On the first code path, priv->p5_intf_sel is either set to
P5_INTF_SEL_PHY_P0 or P5_INTF_SEL_PHY_P4 when mt7530_setup_port5() is run.
On the second code path, priv->p5_intf_sel is set to P5_INTF_SEL_GMAC5 when
mt7530_setup_port5() is run.
Empty the default case which will never run but is needed nonetheless to
handle all the remaining enumeration values.
