Subject: [PATCH 07/19] net/ngbe: special config for YT8531SH-CA PHY
Date: Tue, 18 Jun 2024 15:11:38 +0800 [thread overview]
Message-ID: <20240618071150.21564-8-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20240618071150.21564-1-jiawenwu@trustnetic.com>
YT8531SH-CA PHY will switch to SDS space automatically when UTP and
SDS media are not present, causing failure to link up. Add the special
configuration to fix it.
Fixes: 3d0af7066759 ("net/ngbe: setup PHY link")
Fixes: 1c44384fce76 ("net/ngbe: support custom PHY interfaces")
