Subject: [RFC net-next 04/28] hostap: use ndo_siocdevprivate
Date: Fri, 6 Nov 2020 23:17:19 +0100 [thread overview]
Message-ID: <20201106221743.3271965-5-arnd@kernel.org> (raw)
In-Reply-To: <20201106221743.3271965-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
hostap has a combination of iwpriv ioctls that do not work at
all, and two SIOCDEVPRIVATE commands that work natively but
lack a compat conversion handler.
For the moment, move them over to the new ndo_siocdevprivate
interface and return an error for compat mode.
