I have been experimenting with different revisions to the mbuf api to
improve performance and simplify code. This patch is the first of
several proposed steps towards those goals. The aim of this patch is
two fold;
I would appreciate testing feedback from varied workloads to make sure
there are no bugs before I go forward with this. I have tested only
host oriented networking with a few drivers. It is not anticipated
that there will be any significant incompatibilities introduced with
this round but there is always that possibility.

Finally, I tested the patch on an IBM ThinPad R51. The kernel
hangs on boot, the last messages are (hand transcribed):
iwi0: <Intel(R) PRO/Wireless 2200BG> mem 0xc0214000-0xc0214fff irq 11 at device
2.0 on pci2
iwi0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xc0214000
iwi0: could not allocate rx mbuf
iwi0: could not allocate Rx ring
bpfdetach: was not attached
Never mind, kernel and user land weren't completely in
sync and this might be related to the recent wlan commits.
I'll retry with an up-to-date user land.
I have updated the patch here:

This resolves the !INVARIANTS bug and improves the style as you suggested.
Thanks,
