Is there a good reason the skb refill routine in e1000_alloc_rx_buffers
needs to go and touch and remap skb memory
on already loaded descriptors/ This seems extremely wasteful of
processor cycles when refilling the ring buffer.
I note that the archtiecture has changed and is recycling buffers from
the rx_irq routine and when the routine is called
to refill the ring buffers, a lot of wasteful and needless calls for
map_skb is occurring.
