declance questions

[Florian Lohoff <flo@rfc822.org>]

Hi,
i found out that the transfers of the declance/nfs are VERY bursty.
If you look at an tcpdump you see that you have heavy activity some
seconds (10-30) and then a delay of couple of seconds to minutes.

Also - is it correct that data from&to the ethernet is copied 
via CPU ?

        /*
         * copy 16 Byte chunks
         */
        clen = len >> 4;
        tp = (unsigned short *)to;
        fp = (unsigned short *)from;
        while (clen--) {
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                *tp++ = *fp++;
                tp += 8;
        }

The comment says that there is an misalignment for the skbs ?
But i remember reading in one of the TC DMA Docs TcIA or something
about byte alignment.
