Link Training Configuration
Link Training Configuration describes the parameters controlling the
LTSSM (Link Training and Status State Machine). In the first release it is
only defined and implemented for PCI Express 3.0. This is done with the
<linkTrainingConfigurations> node. It is inserted just before the
<codingConfigurations> node. The following parameters can be
configured as attributes.
