Hi all,
Just noticed in RFC4340
<snip>
5.8.2. Mandatory Option
+--------+
|00000001|
+--------+
Type=1
Mandatory is a single-byte option that marks the immediately
following option as mandatory. Say that the immediately following
option is O. Then the Mandatory option has no effect if the
receiving DCCP endpoint understands and processes O. If the endpoint
does not understand or process O, however, then it MUST reset the
connection using Reset Code 6, "Mandatory Failure".
<snip>
In other places this reset code is refered as "Mandatory Error".
