Run a Multimedia command (MMC) specifying the CDB length.

Browse Source 
The motivation here is for example ot use in is an undocumented
debug command for LG drives (namely E7), whose length is being
miscalculated by mmc_get_cmd_len(); it doesn't follow the usual
code number to length conventions. Patch supplied by SukkoPera.
