LR_ACKID_ILL
Link response received with an ackID that is not outstanding.
The Capture register does not have valid information during this
error detection.
During a recovery attempt by the Tsi576, it issued a link request
control symbol to its link partner in order to attempt to clear the
outstanding port error states. The link response it got back is
supposed to contain the ACK_ID that the link partner is expecting in
the next new packet it receives. The Tsi576 is indicating that it has
already sent a packet with that ACK_ID and has received a packet
accepted control symbol for it, and has moved to the next ACK_ID
value. This value can be found in the
. Therefore, an ACK_ID mismatch
has occurred and until the ACK_IDs are re-aligned, no packet
transfers take place.
