From 818a986e4ebacea2020622e48c8bc04b7f500d89 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 12 Apr 2017 11:23:28 +0200 Subject: cfg80211: move add/change interface monitor flags into params Instead passing both flags, which can be NULL, and vif_params, which are never NULL, move the flags into the vif_params and use BIT(0), which is invalid from userspace, to indicate that the flags were changed. While updating all drivers, fix a small bug in wil6210 where it was setting the flags to 0 instead of leaving them unchanged.
