This SILI bit (suppress incorrect length indicator) is defined only for SSC
READ(6) and READ(16) commands. For other device types bit is part of LBA
field. In the current implementation, it is not checked whether the logical
unit is a SSC device.
Added code for checking the LU type is SSC for SILI bit in READ_6 and READ_16 CDB
