Subject: [PATCH v2 03/25] net/axgbe: fix fluctuations for 1G BELFUSE SFP
Date: Tue, 7 May 2024 18:12:43 +0530 [thread overview]
Message-ID: <20240507124305.2318-3-venkatkumar.ande@amd.com> (raw)
In-Reply-To: <20240507124305.2318-1-venkatkumar.ande@amd.com>
Frequent link up/down events can happen when a Bel Fuse SFP part is
connected to the amd-xgbe device. Try to avoid the frequent link
issues by resetting the PHY as documented in Bel Fuse SFP datasheets.
Without the fix user will see continuous port link up and down.
