NAME

       z8530_tx_begin - Begin packet transmission

SYNOPSIS

       void z8530_tx_begin  (struct z8530_channel * c);

ARGUMENTS

       c      The Z8530 channel to kick

DESCRIPTION

       This  is the speed sensitive side of transmission. If we are called and
       no buffer is being transmitted we commence the next buffer. If  nothing
       is queued we idle the sync.

NOTE

       We  are  handling this code path in the interrupt path, keep it fast or
       bad things will happen.

       Called with the lock held.
