PROBLEM:
  Message logged by Interphase ATM node receiving from another Interphase ATM node.
  EventLog message-pair: (example messages shown)
    <date-time>Ip5515si Warning None...<system-name>LECn-n: rx 802.3 packet too short 
    <date-time>Ip5515si Warning None...<system-name>Len 0  vcc 0/152 

  Note, that at this time, there are no reports of loss of connectivity, loss
  of data or application program errors as a result of this issue.


CAUSE:
  The reporting node has received a valid AAL5 frame that apparently contains
  no data.

  The origin of this kind of frame is another Interphase ATM node.
  The transmitting ATM adapter is installed in a system slot in the 2nd PCI
  bus group.

  The root-cause of this problem is under investigation by Interphase.


SOLUTION:
  Under development.

  Temporary work-around: Move Interphase ATM adapters to the system's primary
  PCI bus group.

  In the example below, moving the adapters to slots 5 or 6 stops the messages.


This issue has been observed under the following conditions:
  Compaq Proliant 2500, Dual 200 MHz CPU, 96 MB RAM
  Windows NT 4.0 w/ServicePack-3
  Banyan-Vines "Street Talk for NT" Version 7.5 (active Vines traffic)
  Interphase 5515 and 5575 PCI ATM adapters
  - Installed in slot 2 (2nd PCI bus group)
  - Driver version & part-numbers:
    Version ID 1.0 (SX00168-C02,C03)
    Version ID 1.1 (SX00168-C05)
  - LEC Type: Emulated LAN "Ethernet"
  - ATM Signalling: UNI 3.0 or UNI 3.1
Note: This is an observation and in no way indicates a fault or problem in any
      of the non-Interphase components.
