From 3f3fa5340745c81a2e70a171fb73a44b433d5126 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 27 Jul 2021 15:44:50 +0200 Subject: hostap: use ndo_siocdevprivate 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. Cc: Jouni Malinen Cc: Kalle Valo Signed-off-by: Arnd Bergmann Signed-off-by: David S.
