i read the netcard DEC21140 driver recently, i noticed
that dec21140_stop( ) is called in the dec21140_ioctrl( ) function. But
rtems doesn't tell what to do in the stop( ) function.
Anyone can give some information ?
here is the code for dec21140_stop ( )
dec21140_stop (struct dec21140_softc *sc)
volatile unsigned int *tbase;
struct ifnet *ifp = &sc->arpcom.ac_if;
ifp->if_flags &= ~IFF_RUNNING;
* Stop the transmitter
tbase = sc->base;
st_le32( (tbase+memCSR7), NO_IT);
st_le32( (tbase+memCSR6), CSR6_INIT);
/* free((void*)sc->bufferBase); */
