    net/mac80211/rx.c: fix build error · bf94e17b
    Ingo Molnar authored
    older versions of gcc do not recognize that ieee80211_rx_h_mesh_fwding()
    is unused when CONFIG_MAC80211_MESH is disabled:
    
      net/built-in.o: In function `ieee80211_rx_h_mesh_fwding':
      rx.c:(.text+0xd89af): undefined reference to `mpp_path_lookup'
      rx.c:(.text+0xd89c6): undefined reference to `mpp_path_add'
    
    as this code construct:
    
            if (ieee80211_vif_is_mesh(&sdata->vif))
                    CALL_RXH(ieee80211_rx_h_mesh_fwding);
    
    still causes ieee80211_rx_h_mesh_fwding() to be linked in.
    
    Protect these places with an #ifdef.
    
    commit b0dee578 ("Fix modpost failure when rx handlers are not inlined.")
    solved part of this problem - this patch is still needed.
