# Verifies that a MGMT_ACTIVE_SET request which changes the Network Key is
# applied through the Pending Dataset with the default delay
# (OPENTHREAD_CONFIG_TMF_PENDING_DATASET_DEFAULT_DELAY, 300s), so a key
# change cannot take effect faster than the default delay. An unexpected
# Delay Timer TLV in the Active Dataset is ignored, so the outcome is the
# same whether the request omits the TLV or carries one.
