 * Note that my_alpa field is of 16 bit size. The lowest significant
 * byte contains the real ALPA.  The highest significant bits are
 * used to indicate if the LBIT was set during Loop Initialization.
 *
 * If the NL_Ports on the loop participate in the LIRP and LILP dance
 * as part of Loop Initialization then the presence of an F_Port can
 * be detected by checking for the presence of AL_PA '0x00' in the AL_PA
 * list (That does not however guarantee if there is a violating NL_Port
 * trying to grab AL_PA value of '0x00').
 *
 * Some FCAs may be capable of notifying if the L_BIT was set in the
 * AL_PA bit map. The host should then perform an IMPLICIT LOGO and
 * execute a PLOGI before sending any other command.
