10: 0x2B - 0x2D Physical Device Addressing Method (default 0x82 0x04 0x44)
Consists of 3 hex bytes bb ll tt (bb=busid, ll=lun, tt=target id).
The left hex digit is the bit number of the rightmost field bit in the LUN.
The right hex digit is the number of bits in the field.

Bit 4: Translate QUEUE FULL to BUSY, 0 = Disable, 1 = Enable
Bit 2-3: Reserved.
Bit 1: Enable/Disable Bridge Soft Fibre LUN,1 = Enable, 0 = Disable (FBE)
(uses FibreBridge Soft Fibre LUN byte to determine actual ID)
Bit 0: perform/suppress LUN translations, 1 = perform, 0 = suppress.
