protocol_parity_error:
Originally used for detecting parity error on coherent interface, however, no
parity checks exist. So this logs parity errors on data from the IIO switch on
the inbound path.

10:10 ROS_V 0x0
protocol_rcvd_unexprsp:
A completion has been received from the Coherent Interface that was
unexpected.

wrcache_uncecc_error:
A double bit ECC error was detected within the Write Cache.
2:2 ROS_V 0x0
protocol_rcvd_poison:
A poisoned packet has been received from the Coherent Interface.
1:1 ROS_V 0x0
wrcache_correcc_error:
A single bit ECC error was detected and corrected within the Write Cache.
