If we now only need to left-shift by 1, it implies that there is an additional right-shift by 1 when using ETH mode today. So if built for the DTL-T10000, we should right-shift by 3 to keep things working.

case ETH_MODE:
/* SMB's IOP module layout requires one fewer compensating shift. */
word2 = 0x00021840; // sll $v1, $v0, 1
break;
#endif
default:
#ifdef _DTL_T10000
word2 = 0x00021903; // sra $v1, $v0, 4 For DTL-T10000.
