Subject: [PATCH RFC net-next 2/8] net: phylink: add legacy_pre_march2020 indicator
Date: Tue, 23 Nov 2021 10:00:19 +0000 [thread overview]
Message-ID: <E1mpSb5-00BXoV-IG@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <YZy59OTNCpKoPZT/@shell.armlinux.org.uk>
Add a boolean to phylink_config to indicate whether a driver has not
been updated for the changes in commit 7cceb599d15d ("net: phylink:
avoid mac_config calls"), and thus are reliant on the old behaviour.
We were keying this behaviour on the presence of a PCS, but this
becomes an unreliable indicator when making PCS optional. Hence, we
use a flag instead.
