I have added two new features to the en atm driver.  

 - support of VC/VP shaping and pvctxctl commnad.
 - support of a PVC shadow interface and pvcsif command.

  A shadow interface is intended to use an ATM PVC as an alternative
  serial connection, and to be allocated per PVC basis.
  A shadow interface looks as a point-to-point interface
  and is multicast capable, as opposed to the NBMA 
  (NonBroadcast Multiple Access) model that requires a MARS server.
  A point-to-point interface is useful to run MBone or protocols
  requiring multicast, such as RSVP and IPv6, over a PVC WAN
  connection.

If people like these features, I will commit the changes to the
FreeBSD-current tree.

The source code for both 2.2.x and 3.0 is avaiable from

ftp://ftp.csl.sony.co.jp/pub/kjc/bsdatm-971229.tar.gz


other difference from bsdatm dist1.4:
 - the code base is updated to sync with
	$NetBSD: midway.c,v 1.30 1997/09/29 17:40:38 chuck Exp $
 - code cleanup.
    - remove support of FreeBSD-2.1.x and broken early versions
      of 3.0-SNAP.
    - remove WMAYBE DMA related code for ENI cards. (it doesn't work.)
    - remove updating if_lastchange for every packet.
    - BPF related code is moved to midway.c as it should be.
      (bpfwrite should work if atm_pseudohdr and LLC/SNAP are
      prepended.)
    - BPF link type is changed to DLT_ATM_RFC1483.
      BPF now understands only LLC/SNAP!! (because bpf can't
      handle variable link header length.)
      It is recommended to use LLC/SNAP instead of NULL
      encapsulation for various reasons.  (BPF, IPv6,
      interoperability, etc.)
    - integrate IPv6 support.
    - man pages (en(4), natm(4), pvc(4), pvcsif(8), pvctxctl(8))
