Does this replace pcn(4) which supported the DMA-capable lnc(4) chips as well:

     o   AMD Am53C974/Am79C970/Am79C974 PCnet-PCI
     o   AMD Am79C970A PCnet-PCI II
     o   AMD Am79C971 PCnet-FAST
     o   AMD Am79C972 PCnet-FAST+
     o   AMD Am79C973/Am79C975 PCnet-FAST III
     o   AMD Am79C976 PCnet-PRO
     o   AMD PCnet/Home HomePNA
     o   Allied-Telesis LA-PCI
     o   Contec C-NET(98)S (PC-98)
     o   NEC SV-98/2-B05, B06
