I think the above could be more clear as:

"""
	If temp_prefered_lft is less than the minimum required lifetime (typically
	5 seconds), the preferred lifetime is extended to the minimum required.
	If temp_prefered_lft is greater than temp_valid_lft, the preferred
	lifetime is limited to temp_valid_lft.
"""
