Answering one of my own questions..... According to a chip errata sheet the DM9102A Rev. 0x40 requires double word aligned transmit buffers but earlier revisions (e.g. 0x31) didn't. I guess the tulip driver works well with older revisions only. But my question still remains: How can I get a double word aligned transmit buffer using the network core's sk_buff mechanism ? If I can't do that I'll have to rewrite the driver to use use my own aligned buffers and copy the sk_buff data to them. It's a pity because then it doesn't make much sense to follow that with a DMA transfer.... -- Howard Gray MATRIX Vision GmbH Oppenweiler Germany ** Sent via the linuxppc-embedded mail list.
