GEN_StaleCookieError.seq - Generation of error cause Stale Cookie Error
To check that if a COOKIE-ECHO chunk is received with state cookie
expired, the endpoint should send ERROR message with cause Stale
Cookie Error.

Association is not established between endpoint A and B. Arrange
data in endpoint A such that COOKIE-ECHO chunk with stale cookie
expired is sent to endpoint B.

Measure of Staleness: 32 bits (unsigned integer)
This field contains the difference, in microseconds, between the
current time and the time the State Cookie expired.
The sender of this error cause MAY choose to report how long past
expiration the State Cookie is by including a non-zero value in
the Measure of Staleness field. If the sender does not wish to
provide this information, it should set the Measure of Staleness
field to the value of zero.
