mac80211: fix the problem of forwarding from DS to DS in Mesh (163df6cf) · Commits · 戴 / test

Unicast frame with unknown forwarding information always trigger the path discovery assuming destination is always located inside the MBSS. This patch allows the forwarding to look for mesh gate if path discovery inside the MBSS has failed. Reported-by:
