Message-Id: <20221209081023.19541-1-mengyuanlou@net-swift.com>
Date: Fri, 9 Dec 2022 16:10:23 +0800
From: Mengyuan Lou <mengyuanlou@...-swift.com>
To: netdev@...r.kernel.org
Cc: jiawenwu@...stnetic.com, Mengyuan Lou <mengyuanlou@...-swift.com>
Subject: [PATCH net-next v3] net: ngbe: Add ngbe mdio bus driver.
Add mdio bus register for ngbe.
The internal phy and external phy need to be handled separately.
Add phy changed event detection.
Signed-off-by: Mengyuan Lou <mengyuanlou@...-swift.com>
