Subject: [PATCH net-next 09/15] net: phy: realtek: read standard MMD register for rtlgen speed capability
Date: Wed, 20 Dec 2023 16:55:12 +0100 [thread overview]
Message-ID: <20231220155518.15692-10-kabel@kernel.org> (raw)
In-Reply-To: <20231220155518.15692-1-kabel@kernel.org>
Read the standard "PMA/PMD speed ability" register instead of it's
vendor specific alias via paging in rtlgen_supports_2_5gbps(), which is
used by the .match_phy_device method.
