11.3  LAN Shared Memory Device Driver

  Local Area Network (LAN) communications between
  OpenVMS Galaxy instances are supported by a new Ethernet
  LAN shared memory driver.  This LAN driver communi-
  cates to other instances in the same Galaxy through shared
  memory.  The ability to communicate to another instance
  through shared memory provides performance benefits over
  traditional LANs.

  The LAN shared memory driver, SYS$EBDRIVER, is loaded
  by the following command:

  $mcr  sysman
  io  conn  eba/driver=sys$ebdriver/noadapter

  In a future release, this device driver will be loaded au-
  tomatically.  For OpenVMS Version 7.2, in order for LAN
  protocols to automatically start over this LAN device (EBAn,
  where n is the unit number), the procedure for loading
  this driver should be added to the configuration procedure:

  sys$manager:syconfig.com  .

  The LAN driver emulates an Ethernet LAN with frame for-
  mats the same as Ethernet/IEEE 802.3 but with maximum
  frame size increased from 1518 to 7360 bytes.  The LAN
  driver presents a standard OpenVMS QIO and VCI interface
  to applications.  All existing QIO and VCI LAN applications
  should work unchanged.
