PROBLEM:  (QARs 73347, 73916)    (Patch ID: OSF500-058)
********

This patch updates the lfa ATM driver to V1.0.16 and fixes the following
two ATM driver problems:

     - Filesystems mounted using NFS over an ATM connection
       which uses either the Compaq HE622 or HE155 ATM adapters
       can experience soft hangs. When this happens, a file transfer
       operation will not complete (typically a write from the client to
      the server) or an unmount operation will hang.  The rest of the
       system is still operational.

    - Under certain configurations, the ATM adapter can hang.
      When this occurs, the ATM subsystem cannot be successfully
      shut down and then restarted.  Following an "atmconfig down
      driver=lfa<#>" command, the driver and ATM stack enters an
      unrecoverable state where no further operations are allowed.
      The state remains "GOING DOWN" (as reported by the
      command "atmconfig status driver=lfa<#>") until the next
      system boot.

PROBLEM: (77506, 77655) (PATCH ID: OSF500-188)
********
This patch fixes a number of problems in the driver shutdown path. All the 
problems would result in a kernel memory fault panic but that panic might
not manifest itself until the driver was restarted.  
This patch also enhances the driver by making the following changes:

   - The deferred interrupt processing path (attribute minimal_isr set to 1)
     has been modified to perform much better.  This method of handling
     interrupts is now the default.

   - The time between when an adapter receives a frame and when it generates
     an interrupt to the host system has been shortened from 768 to 100
     microseconds.  This reduces the receive processing latency.

   - The model number string which prints out when the adapter is configured
     will display the -UA or -FA extension, reflecting the type of media
     used by the adapter.
