When the value in this register is modified, the PRBS counter
associated with this seed is reset to the seed value and re-starts

Link Error Type.
This field can be programmed to select the
type of error monitored by the Autonomous Link Reliability Man-
agement logic.
0x0 - Individual Bit Errors (i.e., LCRC Errors)
0x1 - Link State Errors (i.e., LTSSM transitioning from the L0 to
the Recovery state due to the following link errors: clock com-
pensation FIFO underflow/overflow, electrical idle detected/
inferred on the receiver, lane de-skew aligner errors, and DL
layer errors that trigger link retraining).
Note that it is only possible to count link errors that cause the
port to initiate a link transition to Recovery. Link errors that
cause the link partner to initiate entry into the Recovery state
are not counted.
