FDDI/9000 EISA Adapter Release Notes
Patches and Fixes in Version B.11.00.07
3. The system panics with a ‘Data page
fault’ when promiscuous mode is
repeatedly turned on and off over the
EISA FDDI interface.
3. 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. Apart from correcting
the order of steps followed to disable
promiscuous mode, the driver code has
been changed to synchronize access to
the promiscuous mode related data
structures by using locks.
4. The system may panic with a ‘Data
page fault’ when the EISA FDDI
interface is operating in promiscuous
mode with heavy inbound traffic.
4. 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. The code
has been modified to insure that the
inbound buffer will be freed only once.
5. Aborts/Underruns are observed
when frames larger than 3000 bytes
are transmitted, with EISA SCSI
present on the system.
5. This problem was fixed in an earlier
patch by increasing the transmit FIFO
watermark on the FSI chip to MTU
size. However, the FIFO watermark
was getting reset to the default value
after a card reset. Also, the transmit
FIFO watermark is now set to MTU
size after a card reset.
