Subject: [PATCH 14/18] net: Update Realtek r8169 driver
Date: Thu, 4 May 2023 10:17:41 +0200 [thread overview]
Message-ID: <20230504081745.305841-15-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230504081745.305841-1-s.hauer@pengutronix.de>
This updates the r8169 driver from Linux-6.3-rc7. The driver code itself
is mostly taken from the old driver, but all the initialization code and
file structure has been taken from Linux. Tested on a RTL8125 chip.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
