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.
