I'm committing changes to mark various network drivers' interrupt handlers
MPSAFE. To insure folks have a way to backout if they hit problems I've also
added a tunable that lets you disable this w/o rebuilding your kernel. By
default all network drivers that register an interrupt handler INTR_MPSAFE
are setup to run their ISR w/o Giant. If you want to defeat this w/o
changing the code you can set
debug.mpsafenet=0
from the loader when booting and the MPSAFE bit will automatically be removed.
I plan to use this to also control forthcoming changes for registering MPSAFE
netisrs.
The following drivers are marked MPSAFE:
ath, em, ep, fxp, sn, wi, sis
I've got changes coming for bge. Other drivers probably can be marked MPSAFE
but I'm only doing it for those drivers that I can test.
