Which spec defines that an ISID is 48 bits? All I know about SCSI registrations is that these involve a transport ID and that that transport ID can be up to 228 bytes long for iSCSI. +AD4- if (isid +ACEAPQ- NULL) +AHs- +AD4- - pr+AF8-reg-+AD4-pr+AF8-reg+AF8-bin+AF8-isid +AD0- get+AF8-unaligned+AF8-be64(isid)+ADs- +AD4- +- if (hex2bin((u8 +ACo-)+ACY-pr+AF8-reg-+AD4-pr+AF8-reg+AF8-bin+AF8-isid, isid, 6)) +AHs- +AD4- +- pr+AF8-err(+ACI-Invalid isid +ACU-s+AFw-n+ACI-, isid)+ADs- +AD4- +- goto free+AF8-reg+ADs- +AD4- +- +AH0- Why is it necessary to convert the ISID from hex to binary format? If this conversion is necessary, isn't that something that should be handled by the iSCSI target driver instead of the target core? Thanks, Bart.
