    [PATCH] macsonic/jazzsonic network drivers update · efcce839
    Finn Thain 提交于
    The purpose of this patch:
    
    - Adopt the DMA API (jazzsonic, macsonic & core driver).
    
    - Adopt the driver model (macsonic).
    
    This part was cribbed from jazzsonic. As a consequence, macsonic once
    again works as a module. Driver model is also used by the DMA calls.
    
    - Support 16 bit cards (macsonic & core driver, also affects jazzsonic)
    
    This code was adapted from the mac68k linux 2.2 kernel, where it has
    languished for a long time.
    
    - Support more 32-bit mac cards (macsonic)
    
    Also from mac68k repo.
    
    - Zero-copy buffer handling (core driver)
    
    Provides a nice performance improvement. The new algorithm incidentally
    helped to replace the old Jazz DMA code.
    
    The patch was tested on a variety of macs (several 32-bit quadra built-in
    NICs, a 16-bit LC PDS NIC and a 16-bit comm-slot NIC), and also on MIPS
    Jazz.
