Subject: [PATCH net-next 08/12] net: phylink: allow attaching phy for SFP modules on 802.3z mode
Date: Fri, 30 Sep 2022 16:21:06 +0200 [thread overview]
Message-ID: <20220930142110.15372-9-kabel@kernel.org> (raw)
In-Reply-To: <20220930142110.15372-1-kabel@kernel.org>
Some SFPs may contain an internal PHY which may in some cases want to
connect with the host interface in 1000base-x/2500base-x mode.
Do not fail if such PHY is being attached in one of these PHY interface
modes.
