Subject: [PATCH 07/24] net/axgbe: check fluctuations for 1G BELFUSE SFP
Date: Fri, 12 Apr 2024 08:52:32 -0400 [thread overview]
Message-ID: <20240412125249.10625-7-VenkatKumar.Ande@amd.com> (raw)
In-Reply-To: <20240412125249.10625-1-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.
