Subject: [RFC net-next PATCH 13/16] net: phy: Export get_phy_c22_id
Date: Mon, 4 Oct 2021 15:15:24 -0400 [thread overview]
Message-ID: <20211004191527.1610759-14-sean.anderson@seco.com> (raw)
In-Reply-To: <20211004191527.1610759-1-sean.anderson@seco.com>
This function is useful when probing MDIO devices which present a
phy-like interface despite not using the Linux ethernet phy subsystem.
