To reduce the possiblity of timing attacks, the size has been cut to 8KB + 256 bytes in contrast to 16KB in the generic implementation. That is not perfect but at least a good tradeoff for CPU limited router devices. v2 changes - comment source of tables - use macros for rotated value expansion Signed-off-by: Markus Stockhausen **************************************************************************** Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.
