LAN_FLAGS

   (Alpha and Integrity servers) LAN_FLAGS is a bit mask used to
   enable features in the local area networks port drivers and
   support code. The default value for LAN_FLAGS is 0.

   The bit definitions are as follows:

   Bit        Description

   0          The default of zero indicates that ATM devices run in
              SONET mode. If set to 1, this bit indicates ATM devices
              run in SDH mode.

   1          If set, this bit enables a subset of the ATM trace
              and debug messages in the LAN port drivers and support
              code.

   2          If set, this bit enables all ATM trace and debug
              messages in the LAN port drivers and support code.

   3          If set, this bit runs UNI 3.0 over all ATM adapters.
              (Auto-sensing of the ATM UNI version is enabled if both
              bit 3 and bit 4 are off (0).)

   4          If set, this bit runs UNI 3.1 over all ATM adapters.
              (Auto-sensing of the ATM UNI version is enabled if both
              bit 3 and bit 4 are off (0).)

   5          If set, disables auto-negotiation over all Gigabit
              Ethernet Adapters.

   6          If set, enables the use of jumbo frames over all
              Gigabit Ethernet Adapters.

   7          Reserved.

   8          If set, disables the use of flow control over all LAN
              adapters that support flow control.

   9          Reserved.

   10         Reserved.

   11         If set, disables the logging of error log entries by
              LAN drivers.

   12         If set, enables a fast timeout on transmit requests,
              usually between 1 and 1.2 seconds instead of 3 to 4
              seconds, for most LAN drivers.

   13         If set, transmits that are given to the LAN device
              and never completed by the device (transmit timeout
              condition) are completed with error status (SS$_ABORT)
              rather than success status (SS$_NORMAL).

   LAN_FLAGS is a DYNAMIC parameter.
