ENUM_B
An enumeration boundary aware system enumeration algorithm
honors this flag. The algorithm on either the ingress or egress
port will not enumerate past a port with this bit set. This provides
for software enforced enumeration domains with the S-RIO
fabric. The device simply stores whatever value is written into this
field.

ERR_MASK
Suppress packet re-transmission on CRC error.
0b0000_0000 = Error recovery suppression disabled
0bxxxx_xxx1 = Suppress CRF = 0, priority 0 re-transmission
0bxxxx_xx1x - Suppress CRF = 0, priority 1 re-transmission
0bxxxx_x1xx - Suppress CRF = 0, priority 2 re-transmission
0bxxxx_1xxx - Suppress CRF = 0, priority 3 re-transmission
0bxxx1_xxxx - Suppress CRF = 1, priority 0 re-transmission
0bxx1x_xxxx - Suppress CRF = 1, priority 1 re-transmission
0bx1xx_xxxx - Suppress CRF = 1, priority 2 re-transmission
0b1xxx_xxxx - Suppress CRF = 1, priority 3 re-transmission
Either set all bits or no bits in this field to ensure consistent
operation when a packet’s PRIO or CRF field is corrupted. The
receipt of a packet with a CRC error when the bit that matches
the packet’s priority is set causes the packet to be acknowledged
and dropped. Note that
.OUTPUT_DROP is not set. Instead,
Implementation Specific Error Detect Register
.CRC_EVENT is
set on the receiving port.
