[PATCH AUTOSEL 5.4 59/73] mac80211: Do not send mesh HWMP PREQ if HWMP is disabled

[Sasha Levin]

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

[ Upstream commit ba32679cac50c38fdf488296f96b1f3175532b8e ]

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.
