Message-Id: <20210720144638.2859828-17-arnd@kernel.org>
Date: Tue, 20 Jul 2021 16:46:23 +0200

Subject: [PATCH net-next v2 16/31] qeth: use ndo_siocdevprivate
From: Arnd Bergmann <arnd@...db.de>
qeth has both standard MII ioctls and custom SIOCDEVPRIVATE ones,
all of which work correctly with compat user space.
Move the private ones over to the new ndo_siocdevprivate callback.
Signed-off-by: Arnd Bergmann <arnd@...db.de>
