sys/net : hfsc.c
Log message:
have the timeout call if qstart via the serialiser isntead of directly
hfsc schedules a timeout to keep traffic moving if somethings has been
delayed an no other tx activity has occurred. that timeout was calling
(*ifp->if_qstart)(ifq) rather than ifq_start. the latter prevents
concurrent calls to if_qstart.
without this change bjorn ketelaars on misc@ was experiencing weird
pauses in traffic and lockups because the tx ring was corrupted
because re_start was run concurrently, once from the stack and once
from hfsc.
thanks to bjorn ketelaars for debugging, and mikeb@ for most of the
legwork in diagnosing the problem.
ok mikeb@
