network02.patch - MPSAFE network interrupt

[Matthew Dillon]

    Here's an update to the networking patch:

	fetch http://apollo.backplane.com/DFlyMisc/network02.patch

    The patch is almost exactly the last patch but with a bug in if_re 
    fixed (Sepherosa Ziehau).

    I'm still on track for a monday commit.  There are two other issues
    related to the work, but they can be handled in followup commits. 

    Once I get this in I will go through recent cleanups posted to submit@
    and get those in as well.
