Hi hi,

I must admit i am not a podulebus expert but the following patch looks good 
to me :

==========================

But ... it is only performing worse :(( ... the reason i re-implemented it 
was that i suspected that the multiple writing on the podulebus was 
faulted.... since the EtherN doesnt work.

The problem with the EtherN is narowed to this: pinging with `ping -s213
a.b.c.d' works fine but `ping -s214 a.b.c.d' faults.... with the error :
"ne0: remote transmit DMA failed to complete" .... given the packet length
this indicates that transfers bigger than 255 bytes go wrong... why??

As an expiriment i already updated the timeout constant in 
../dev/ic/ne2000.c but that didnt help ... maybe it needs to be 1e9 or so 
but normal values don't help :( .... I allready tried 100000.

Another thing is that the fowllowing has the wrong spacing:
        /* Set up DMA byte count. */
        bus_space_write_1(nict, nich, ED_P0_RBCR0, savelen);
        bus_space_write_1(nict, nich, ED_P0_RBCR1, savelen >> 8);

with :
        struct dp8390_softc *sc; 
        bus_space_tag_t nict = sc->sc_regt; 
        bus_space_handle_t nich = sc->sc_regh;

.... any ideas will be welcome !!! this might be only hurdle to get full NC 
support.

Cheers,
Reinoud
