Running mt7530_setup_port5() from mt7530_setup() used to handle all cases
of configuring port 5, including phylink.

Setting priv->p5_interface under mt7530_setup_port5() makes sure that
mt7530_setup_port5() from mt753x_phylink_mac_config() won't run.

The commit ("net: dsa: mt7530: improve code path for setting up port 5")
makes so that mt7530_setup_port5() from mt7530_setup() runs only on
non-phylink cases.

Get rid of unnecessarily setting priv->p5_interface under
mt7530_setup_port5() as port 5 phylink configuration will be done by
running mt7530_setup_port5() from mt753x_phylink_mac_config() now.

Vladimir could you review this too? This is the only patch remaining
without a review or ACK.

Please wait for a few more hours for one of the networking maintainers
to have a chance to see this and ask you to resend, if necessary.

Took me an hour to fix the mailbot:

email is the most quirky thing ever.

Ah, so it was my neomutt encoding email as base64...

I see Arınç's series is now in the proper state, thanks!

Something magical going on there, the email is encoded.. twice?
See the attachment. That's already thru a round of base64 decode 
and there's another copy of the email with base64 inside it :o
Anyway, unwrapping it once is good enough for the bot to see the
command, and enough time spent on this ;)

I don't claim to be an email expert. I've received Vladimir's email with
the "Content-Transfer-Encoding: 8bit" header. The body was plaintext, not
base64 encoded. I have checked how the netdev mailing list distributed
Vladimir's email, its body is plaintext as well, not base64 encoded. Only
the linux-arm-kernel mailing list distributed the body base64 encoded, the
header is "Content-Transfer-Encoding: base64".

And the attachment you've provided seems to be from the raw output of
lore.kernel.org/all which seems to put together the email distribution from
all mailing lists.

raw from all:

https://lore.kernel.org/all/20240129125241.gu4srgufad6hpwor@skbuf/raw

raw from netdev:

https://lore.kernel.org/netdev/20240129125241.gu4srgufad6hpwor@skbuf/raw

raw from linux-arm-kernel:

https://lore.kernel.org/linux-arm-kernel/20240129125241.gu4srgufad6hpwor@skbuf/raw

I don't know which mailing list mailbot looks at in case of an email is
sent with multiple mailing lists being CC'd or TO'd. It seems to be that it
looked at linux-arm-kernel in this instance.

It's the Python library that base-encodes it for some reason :o
