Subject: [PATCH 09/30] net: dsa: mt7530: improve code path for setting up port
|
||
5
|
||
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()
|
||
|
||
Currently mt7530_setup_port5() from mt7530_setup() always runs. If port 5
|
||
is used as a CPU, DSA, or user port, mt7530_setup_port5() from
|
||
mt753x_phylink_mac_config() won't run. That is because priv->p5_interface
|
||
set on mt7530_setup_port5() will match state->interface on
|
||
mt753x_phylink_mac_config() which will stop running mt7530_setup_port5()
|
||
again.
|
||
|
||
Therefore, mt7530_setup_port5() will never run from
|
||
mt753x_phylink_mac_config().
|
||
|
||
Address this by not running mt7530_setup_port5() from mt7530_setup() if
|
||
port 5 is used as a CPU, DSA, or user port. This driver isn't in the
|
||
dsa_switches_apply_workarounds[] array so phylink will always be present.
|
||
|
||
To keep the cases where port 5 isn't controlled by phylink working as
|
||
before, preserve the mt7530_setup_port5() call from mt7530_setup().
|
||
|
||
Do not set priv->p5_intf_sel to P5_DISABLED. It is already set to that when
|
||
"priv" is allocated.
|
||
|
||
Move setting the interface to a more specific location. It's supposed to be
|
||
overwritten if PHY muxing is detected.
|
||
|
||
Improve the comment which explains the process.
