From: "Tan, Tee Min" <tee.min.tan@linux.intel.com>

Add cur_link_an_mode into phy_device struct for PHY drivers to
communicate the in-band AN mode setting with phylink framework.

As there is a mechanism in PHY drivers to switch the PHY interface
between SGMII and 2500BaseX according to link speed. In this case,
the in-band AN mode should be switching based on the PHY interface
as well, if the PHY interface has been changed/updated by PHY driver.

For e.g., disable in-band AN in 2500BaseX mode, or enable in-band AN
back for SGMII mode (10/100/1000Mbps).

Hi Choong Yong Liang,

Please consider adding cur_link_an_mode to the kernel doc
for struct phy_device - which is above the definition of struct phy_device.

This looks like it's grabbing something from phylink and stuffing it
into phylib.  However, I have no idea, because I don't seem to have
received the original patches. I'm guessing the reason is:

2023-06-22 05:21:24 1qCBoy-0003ji-G9 H=mga03.intel.com
[134.134.136.65]:57703 I=[78.32.30.218]:25
X=TLS1.2:ECDHE_SECP521R1__RSA_SHA512__AES_256_GCM:256
F=<yong.liang.choong@linux.intel.com> rejected after DATA: unqualified
address not permitted: failing address in "Cc:" header is: Tan

Which I suspect came from:

	Tan, Tee Min <tee.min.tan@linux.intel.com>

and someone doesn't realise that a "," in the display-name part of
an address *must* be quoted, otherwise "," is taken to be a separator
in the address list.

Consequently, it has now become:

	Tan@web.codeaurora.org, Tee Min <tee.min.tan@linux.intel.com>,

It should have been:

	"Tan, Tee Min" <tee.min.tan@linux.intel.com>

with the double-quotes.

Please do not review this series further, but instead, please can the
author repost it forthwith with correct conformant headers so that a
proper review can be undertaken by all?

Thanks.

Hi Russell,

Sorry for not noticing this myself.
I agree that we should wait for a properly formed post as you suggest.
Choong Yong Liang June 23, 2023, 5:57 a.m. UTC | #4 
Hi Simon,

I will update it in v2. Thank you.

Hi Russell,

Thank you for pointing that out.
I will fix it and send out version 2.
