NAME

       z8530_dma_status -  Handle a DMA status exception

SYNOPSIS

       void z8530_dma_status (struct z8530_channel *chan);

ARGUMENTS

       chan         Z8530 channel to process

DESCRIPTION

       A  status event occurred on the Z8530. We receive these for two reasons
       when in DMA mode. Firstly if we finished a packet transfer we  get  one
       and kick the next packet out. Secondly we may see a DCD change and have
       to poke the protocol layer.
