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

|
||
|
||
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.
