 * Instruction from Teranetics:  Once you detect link is up, go

 * may want to qualify it by first checking Register 30.1.7:6 and
 * making sure it reads "01" (Auto-Neg Complete).
 *
 * If this function is called when the link is down or before auto-
 * negotiation has completed, then the speed of the PHY is not certain.
 * In such cases, this function returns 1G as the default speed with
 * NXGE_OK status instead of NXGE_ERROR.  It is OK to initialize the
 * driver based on a default speed because this function will be called
 * again when the link comes up.  Returning NXGE_ERROR, which may
 * cause brutal chain reaction in caller functions, is not necessary.
