Benjamin Berg c2dfce3d29 wifi: mac80211: do not offer a mesh path if forwarding is disabled ... [ Upstream commit cf1b684a06 ] When processing a PREQ the code would always check whether we have a mesh path locally and reply accordingly. However, when forwarding is disabled then we should not reply with this information as we will not forward data packets down that path. Move the check for dot11MeshForwarding up in the function and skip the mesh path lookup in that case. In the else block, set forward to false so that the rest of the function becomes a no-op and the dot11MeshForwarding check does not need to be duplicated. This explains an effect observed in the Freifunk community where mesh forwarding is disabled. In that case a mesh with three STAs and only bad links in between them, individual STAs would occionally have indirect mpath entries. This should not have happened.
