Subject: [PATCH net-next 2/5] net: phylink: allow attaching phy for SFP modules on 802.3z mode
Date: Wed, 28 Oct 2020 23:14:24 +0100	[thread overview]
Message-ID: <20201028221427.22968-3-kabel@kernel.org> (raw)
In-Reply-To: <20201028221427.22968-1-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.
