Subject: [PATCH] net: remove smc911x driver

From: Arnd Bergmann <[email-masked]>
Date: Mon, 17 Oct 2022 14:18:26 +0200

From: Arnd Bergmann <[email-masked]>

This driver was used on Arm and SH machines until 2009, when the
last platforms moved to the smsc911x driver for the same hardware.

Time to retire this version.
