    ltq-deu: Mark lantiq DEU broken
    
    When the ltq_deu_vr9 kernel module is loaded, hostapd does not start any
    more. It fails with this error message:
    daemon.err hostapd: nl80211: kernel reports: key addition failed
    daemon.err hostapd: Interface initialization failed
    
    OpenWrt uses the standard Linux crypto API in the wifi drivers now
    and this probably makes the system offload more crypto operations to
    special hardware like the Lantiq DEU. There is probably a bug in the DEU
    and these operations fail and then hostapd does not start the interface.
    
    Do not include the Lantiq DEU by default any more.
    
    Fixes: FS#3901
    Fixes: 53b6783907f3 ("mac80211: remove patches stripping down crypto support")
