Subject: [PATCH net] net: phylink: allow RGMII/RTBI in-band status
Date: Fri, 19 Aug 2022 17:26:06 +0800 [thread overview]
Message-ID: <20220819092607.2628716-1-dqfext@gmail.com> (raw)
As per RGMII specification v2.0, section 3.4.1, RGMII/RTBI has an
optional in-band status feature where the PHY's link status, speed and
duplex mode can be passed to the MAC.
Allow RGMII/RTBI to use in-band status.
Fixes: 9525ae83959b ("phylink: add phylink infrastructure")
