Subject: [PATCH net-next 11/15] bnxt_en: Add async. event logic for PHY configuration changes.
Date: Sat, 23 Nov 2019 03:26:06 -0500	[thread overview]
Message-ID: <1574497570-22102-12-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1574497570-22102-1-git-send-email-michael.chan@broadcom.com>

If the link settings have been changed by another function sharing the
port, firmware will send us an async. message.  In response, we will
call the new bnxt_init_ethtool_link_settings() function to update
the current settings.
