Subject: [PATCH net-next v2 11/31] tehuti: use ndo_siocdevprivate
Date: Tue, 20 Jul 2021 16:46:18 +0200 [thread overview]
Message-ID: <20210720144638.2859828-12-arnd@kernel.org> (raw)
In-Reply-To: <20210720144638.2859828-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Tehuti only implements private ioctl commands, and implements
them by overriding the ifreq layout, which is broken in
compat mode.
Move it to the ndo_siocdevprivate callback in order to fix this.
