Table 1-2 FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 PHNE_17285 Symptom Defect 3. netstat(1M) used with the -i option shows a large number of inbound errors on the EISA FDDI interface. 4. When the EISA FDDI interface is configured down using the ifconfig(1M) command, an unbound SAP promiscuous stream opened on the interface failed to receive IP/ARP packets coming in on the interface. 5. The system may panic with a 'Data page fault' when the EISA FDDI interface is operating in promiscuous mode with heavy inbound traffic. 6. The system panics with a 'Data page fault' when promiscuous mode is repeatedly turned on and off over the EISA FDDI interface. 3. Packets which were being dropped, either due to the interface being configured down (using the ifconfig(1M) command), or due to the driver not being able to decipher the protocol type of the packet, were counted as inbound errors for IP. 4. When an unbound stream in SAP promiscuous mode is operating over the EISA FDDI interface and the interface is configured down using the ifconfig(1M) command, the driver stops sending IP/ARP packets to the promiscuous stream. The expected behavior is to continue sending these packets to the promiscuous stream. 5. Under heavy network traffic, with the EISA FDDI interface in promiscuous mode, when a call to allocate memory failed, an inbound buffer could be freed more than once, resulting in a system panic. 6. When promiscuous mode is turned on/off repeatedly, there was a time window during which the stream, which had previously turned promiscuous mode off, was closed before the card's promiscuous mode was turned off by the driver. The time window was introduced because of the order in which the driver carried out the steps to disable promiscuous mode on the interface. Due to this time window, some packets were still sent to a non-existent stream, leading to a system panic. 16 Chapter 1
