Hi,

There's a change in the MAC's ability to support Pause, so we should :

- Recompute the pl->supported field. Update the
config.mac_capabilities with the
  new pause settings, calling phylink_validate() should do the trick I think,

this

  will rebuild the capability list:

  phylink_validate(pl, pl->supported, &pl->link_config);

- Then update the pl->link_config.pause,

- Then update the pause advertising, like done in phylink_setpauseparam
  ( I think, everything that comes after pl->state_mutex gets released in
   phylink_ethtool_set_pauseparam)

Ideally, the logic to update the advertising and re-trigger a
negociation should be factored out in a private helper, then reused
from both this path (MAC updates pause support) and the

phylink_ethtool_set_pauseparam path.

Thanks for review and helpful suggestions.

I agree with your suggestion to factor out the logic into a private helper and

reuse it for both phylink_ethtool_set_pauseparam() and
phylink_update_mac_pause_capabilities().

Here is the refactored logic. I want to share this specific part with you for a

quick check before I submit v7 patch.

I'm currently attending the netdev conference, It'll take a few days for me to
look at this, sorry about that :/

Maxime

Just a gentle ping on this thread. Could you please take a quick look at this refactored logic whenever you are free? Any suggestion would be greatly appreciated.

Thanks for the ping, I just looked at it from a high level and this is the
thing I had in mind yes :)

I think you can post a new revision then.

Thanks for that work,

Maxime
