68ece75839 Remove the ATMIOCENA and ATMIOCDIS ioctl. Everyting has been converted
to use the new OPENVCC and CLOSEVCC calls that allow the sepcification
of traffic parameters for the connections.

a808105d63 Remove the last vestiges of ATM raw mode. This has not been useful for a
long time and has already been removed from the only driver that supported
it (en(4)) and from the man page.

59db9a86db Implement a mechanism by which ATM drivers can inform interested
parts of the system about certain kinds of events, like changes
in the ABR rate, changes in the carrier state, PVC changes. The
main consumers of these events are the harp(4) pseudo-driver
and the ILMI daemon via ng_atm(4).

09d405d969 Implement an utility function that can be used by device drivers to
implement the ATMIOCGVCCS ioctls. This routine handles changing
VCC tables (which can occure because we cannot hold the driver mutex
while allocating memory) with a loop and a re-allocation, should the
table not fit in the allocated memory.

21a023e9c8 Add identifiers for ProSum's and IDT's cards that are based on
the IDT77252 chip. The driver will follow soon.

918c6c0c7e ATM_PH_LLCSNAP and ATMIO_FLAG_LLCSNAP must have the same value, so
define one in terms of the other.

7d361237dc Fix the breakage introduced by rev. 1.43 of sys/dev/midway.c (don't commit
on friday 13th and without making a universe). This adds struct and
constant definitions for ATM traffic parameters and re-enables the
build of the midway driver.

2102bdf21a Define a link layer MIB for ATM. Most fields of this MIB are needed by
ILMI daemons. Factor out common softc fields for all ATM interfaces that
need to be externally visible into an ifatm structure and make the midway
driver using this structure and fill the MIB.

d2c96fc51f Add module data and version to the atm_subr and reference this info from the
(currently) only consumer (en).

Add a sysctl node hw.atm where the atm drivers will hook on their hardware
sysctl sub-trees.

Make atm_ifattach call if_attach and remove the corresponding call to if_attach
from en. Create atm_ifdetach and use that in en.

While the last change actually changes the interface this is not a problem in
practice because the only other consumer of this API is an older LANAI driver
on the net, that is not ready for current anyway.

57648f8aae This corrects a longstanding endian bug in processing LLC/SNAP encoded
frames. A comment in if_atm.h suggests that both macros, that for extracting
the ethertype and that for inserting it, handle their argument in host
byte order. In fact, the inserting macro treated its argument as an opposite
host order short and the calling code feeds it the result of htons(). This
happens to work on i386, but fails on sparc. Make the macro use real host
endianess.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

0ce8bd9571 clean up en atm driver
o fix DDB support
   - include "opt_ddb.h"
   - fix Debugger() arg
   pointed out by bde

 o back out pvc shadow interface support
   - it is currently not used
   - to make it easier to merge another implementation

 o misc minor cleanup

4f53e3cc7a update ATM driver. (base version: midway.c 1.67 --> 1.68)
several new features are added:
	- support vc/vp shaping
	- support pvc shadow interface

code cleanup:
	- remove WMAYBE related code.  ENI WMAYBE DMA doen'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.)

the code has been used for months in ALTQ and KAME IPv6.

OKed by phk long time ago.
