 Parameters:
+@table @option
+@item amount
 A numeral string, whose value is related to how often output bytes will
 be modified. Therefore, values below or equal to 0 are forbidden, and
 the lower the more frequent bytes will be modified, with 1 meaning
 every byte is modified.

+A numeral string, whose value is related to how often packets will be dropped.
