/*
 * CAN rtnetlink attribute contents in detail
 *
 * CGW_XXX_IF (length 4 bytes):
 * Sets an interface index for source/destination network interfaces.
 * For the CAN->CAN gwtype the indices of _two_ CAN interfaces are mandatory.
 *
 * CGW_FILTER (length 8 bytes):
 * Sets a CAN receive filter for the gateway job specified by the
 * struct can_filter described in include/linux/can.h
 *
 * CGW_MOD_(AND|OR|XOR|SET) (length 17 bytes):
 * Specifies a modification that's done to a received CAN frame before it is
 * send out to the destination interface.
 *
 * <struct can_frame> data used as operator
 * <u8> affected CAN frame elements
 *
 * CGW_LIM_HOPS (length 1 byte):
 * Limit the number of hops of this specific rule. Usually the received CAN
 * frame can be processed as much as 'max_hops' times (which is given at module
 * load time of the can-gw module). This value is used to reduce the number of
 * possible hops for this gateway rule to a value smaller then max_hops.
 *
 * CGW_MOD_UID (length 4 bytes):
 * Optional non-zero user defined routing job identifier to alter existing
 * modification settings at runtime.
 *
 * CGW_CS_XOR (length 4 bytes):
 * Set a simple XOR checksum starting with an initial value into
 * data[result-idx] using data[start-idx] .. data[end-idx]
 *
 * The XOR checksum is calculated like this:
 *
 * xor = init_xor_val
 *
 * for (i = from_idx .. to_idx)
 *      xor ^= can_frame.data[i]
 *
 * can_frame.data[ result_idx ] = xor
 *
 * CGW_CS_CRC8 (length 282 bytes):
 * Set a CRC8 value into data[result-idx] using a given 256 byte CRC8 table,
 * a given initial value and a defined input data[start-idx] .. data[end-idx].
 * Finally the result value is XOR'ed with the final_xor_val.
 *
 * The CRC8 checksum is calculated like this:
 *
 * crc = init_crc_val
 *
 * for (i = from_idx .. to_idx)
 *      crc = crctab[ crc ^ can_frame.data[i] ]
 *
 * can_frame.data[ result_idx ] = crc ^ final_xor_val
 *
 * The calculated CRC may contain additional source data elements that can be
 * defined in the handling of 'checksum profiles' e.g. shown in AUTOSAR specs
 * like http://www.autosar.org/download/R4.0/AUTOSAR_SWS_E2ELibrary.pdf
 * E.g. the profile_data[] may contain additional u8 values (called DATA_IDs)
 * that are used depending on counter values inside the CAN frame data[].
 * So far only three profiles have been implemented for illustration.
 *
 * Remark: In general the attribute data is a linear buffer.
 *         Beware of sending unpacked or aligned structs!
