Table 34 Port 0 Control CSR
Output Degraded-encountered:
Output port has encountered a degraded condition, meaning that the
Error Rate Counter has met or exceeded the port’s degraded error
threshold. Once set remains set until written with a logic 1 to clear.
Once cleared, will not assert again unless the Error Rate Counter
dips below the port’s degraded error threshold and then meets or
exceeds it again.
Output Failed-encountered:
Output port has encountered a failed condition, meaning that the
Error Rate Counter has met or exceeded the port’s failed error
threshold. Once set, remains set until written with a logic 1 to clear.
Once cleared, will not assert again unless the Error Rate Counter
dips below the port’s failed error threshold and then meets or
exceeds it again.
Output Packet-dropped:
Output port has discarded a packet. A packet will be discarded if:
1. it is received while OFE is set and drop packet enable is set and
stop on port failed is set.
2. it is received while output buffer drain enable is set.
2. it is not-accepted by the link-partner while error rate failed thresh-
old trigger is met or exceeded and link-response returns expected
ackID.
Once set, it remains set until written with a logic 1 to clear.
Reserved.
Port Type, this indicates the port type (read-only):
1b0 - Port receiver/drivers are enabled
1b1 - Port receivers/drivers are disabled and are unable to receive/
transmit any packets or control symbols
Port Lockout:
1b0 - The packets that may be received and issued are controlled by
the state of the OPE and IPE bits.
1b1 - This port is stopped and is not enabled to issue or receive any
packets.
Drop Packet Enable:
This bit is used with the Stop on Port Failed-encountered Enable bit
to force certain behavior when the Error Rate Failed Threshold has
been met or exceeded.
Stop on Port Failed-encountered Enable:
This bit is used with the Drop Packet Enable bit to force certain
behavior when the Error Rate Threshold has been met or excessed.
