So I'll apply the original unrolling patch for now.

The patch must be changed to use __qdisc_dequeue_head() instead of
__skb_dequeue() or we screw up the backlog.

Ok, good thing the patch didn't apply correctly anyways :)

Oh well, I was unaware of last changes in 2.6.13-rc1 :(

Given the fact that the PFIFO_FAST_BANDS macro was introduced, I wonder if the patch should be this one or not...
Should we assume PFIFO_FAST_BANDS will stay at 3 or what ?

[NET] : unroll a small loop in pfifo_fast_dequeue(). Compiler generates better code.
     oprofile says this function uses now 0.29% instead of 1.22 %, on a x86_64 target.
