[Intel-wired-lan] [PATCH iwl-next v5] i40e: add restore default speed when changed PHY doesn't support it

[Intel-wired-lan] [PATCH iwl-next v5] i40e: add restore default speed when changed PHY doesn't support it

[Aleksandr Loktionov]

Currently, there was no link after plugging a different type of PHY
module if user forced previous PHY specific link type/speed before.

Add reset link speed settings to the default values for PHY module,
if different PHY module is inserted and currently defined user-specified
speed is not compatible with this module.

good move!,
now you have to focus on the rules more, like those:
do not post next version before 24h of prev one;

more metadata:
I would remove the word 'add' from the Subject line;
You still need to change author to Radoslaw.

I don't agree, because it's not a fix it's a new feature implementation => 'add' feature.
If you have a better idea please suggest a full commit title which fits 72 chars. What I have now it my best.

The patch was seriously modified, so we are co-authors.
And I'd better leave my e-mail, which is still alive, on top for better community support.

i40e: support restoring default speed when changed PHY does not

sure, my rule of thumb then is to put bigger contributor as main author,
and the other/s as co-authors,
perhaps some people believe that chronologically first should be the main?

I always try to split patch into more
(each of them still being of value when standing alone ofc).

anyway, it's just a comment, not change-request :)

> And I'd better leave my e-mail, which is still alive, on top for better community support.

doesn't matter, your address is there as a Submitter anyway :)
