147  *	BGE_PHY_STABLE_TIME is the period for which the contents of the

149  *	that the link has come up.  [Sometimes the link comes up, only
150  *	to go down again within a short time as the autonegotiation

159  *	BGE_LINK_SETTLE_TIME is the period during which we regard link
160  *	up/down cycles as an normal event after resetting/reprogramming

162  *	the log only, not the console.  At any other time, link change
163  *	events are regarded as unexpected and sent to both console & log.
164  *
165  *	These latter two values have no theoretical justification, but
166  *	are derived from observations and heuristics - the values below
167  *	just seem to work quite well.
