 - Skip chained generated rules that exceed the maximum number of function calls
 - Fixed incorrect plaintext check for 25400 and 26610. Increased plaintext check to 32 bytes to prevent false positives.
 - Fixed bug in --stdout that caused certain rules to malfunction
+- Fixed incompatible pointer types (salt1 and salt2 buf) in 3730 a3 kernel
