Subject: [PATCH] mac80211: Do not send mesh HWMP PREQ if HWMP is disabled
Date: Thu,  5 Mar 2020 15:04:09 +0100
Message-ID: <20200305140409.12204-1-cavallar@lri.fr> (raw)

From: Nicolas Cavallari <nicolas.cavallari@green-communications.fr>

When trying to transmit to an unknown destination, the mesh code would
unconditionally transmit a HWMP PREQ even if HWMP is not the current
path selection algorithm.
