via-velocity: remove the bounce buffers
Executive summary: the bounce buffers are in my way - they use something like a 64 * 1500 bytes area of PCI consistent area - they are not resized when the MTU changes - they are used - to hand-pad undersized packets. skb_pad anyone ? - to linearize fragmented skbs whose fragment count goes beyond the 7 fragments hardware limit in order to claim scatter-gather support Actually the SG code is commented out and I wonder if it could not be implemented (ab-)using the large send feature of the chipset since the latter should support some multi-descriptor packet transmitting.
