just update the carrier/signal status of the adapter.  initially
configure that state to SIG_UNKNOWN.  the logic to determine the value
of the carrier sysfs value will get the rest right.

i dont believe it is correct either.  no other driver does this because
the carrier status shouldnt be used to reset any of the protocols
running over a pvc or svc.  signalling used a seperate channel (0.5) to
keep track of whether or not you are alive and well (sscop).  i gather
that pvc circuits used ppp to keep track of link state.  so the carrier
state bouncing briefly shouldnt bother them really.
