    ath79: mikrotik: fix network setup for lhg-hb platform
    
    This network setup for MikroTik devices based on the LHG-HB platform
    avoids using the integrated switch and connects the single Ethernet
    port directly. This way, link speed (10/100 Mbps) is properly repor-
    ted by eth0.
    
    Fixes: FS#3309
