Advanced Communications Controller B.03.32.03 Release Notes

The reason for the above problem is that some "break" statements were missing in the switch
statement in dsc_card() function of LDM code. It also misses out the setting of "irr.reason"
to indicate different reasons for card disable or halt.
• JAGad21743
Symptoms: During high load activity on the Z7200A OR Z7400A ACC cards, such as X.25
call establishment and clearing on all port, the port may be unable to accept further transmit
requests. The affected port is not usable until the ACC card is restarted.
In the case of X.25 call establishment, the user application may encounter the error return
ENOSPC.
Defect/Fix: The transmit processing for the affected port was stalled, because the firmware
was in an inconsistent state. Two problems in the low level state processing of the frame
protocol have been identified and removed. A workaround has been implemented for an
inconsistent state where the transmit timer was not running, but the transmitter was active.
Additional protection has also been added to interrupt critical state processing.
• JAGad25064
Symptoms: ACC 8 port PCI was sending 1 byte data packet.
Defect/Fix: The default SAM values for N2Z_OUTB_BUFFER_SZ and
N2Z_MAX_ZSTRBUF_PGS were incorrect and have been modified.
