This attribute specifies the types of frames that are sent during the
card test. It must contain at least one of the following values.
loading: A set of 'loading frames' is circulated between the Test
component and the Test component on the target card as rapidly as
possible. This frame type should be selected when the test is
intended to verify the operation of the cards and the backplane
buses under a specified load.
verification: A single 'verification frame' is transmitted to the Test
component on the target card; when the frame is returned, its
contents are verified and the next verification frame in the series is
transmitted. This frame type should be selected when the test is
intended to verify that frames are not being corrupted as they pass
from card to card.
