net: wan: Delete the DLCI / SDLA drivers
The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf30 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

Frame Relay (FR)
|
|
||||||
================
|
|
||||||
|
|
||||||
Frame Relay (FR) support for linux is built into a two tiered system of device
|
|
||||||
drivers. The upper layer implements RFC1490 FR specification, and uses the
|
|
||||||
Data Link Connection Identifier (DLCI) as its hardware address. Usually these
|
|
||||||
are assigned by your network supplier, they give you the number/numbers of
|
|
||||||
the Virtual Connections (VC) assigned to you.
|
|
||||||
|
|
||||||
Each DLCI is a point-to-point link between your machine and a remote one.
|
|
||||||
As such, a separate device is needed to accommodate the routing. Within the
|
|
||||||
net-tools archives is 'dlcicfg'. This program will communicate with the
|
|
||||||
base "DLCI" device, and create new net devices named 'dlci00', 'dlci01'...
|
|
||||||
The configuration script will ask you how many DLCIs you need, as well as
|
|
||||||
how many DLCIs you want to assign to each Frame Relay Access Device (FRAD).
|
|
||||||
|
|
||||||
The DLCI uses a number of function calls to communicate with the FRAD, all
|
|
||||||
of which are stored in the FRAD's private data area. assoc/deassoc,
|
|
||||||
activate/deactivate and dlci_config. The DLCI supplies a receive function
|
|
||||||
to the FRAD to accept incoming packets.
|
|
||||||
|
|
||||||
With this initial offering, only 1 FRAD driver is available. With many thanks
|
|
||||||
to Sangoma Technologies, David Mandelstam & Gene Kozin, the S502A, S502E &
|
|
||||||
S508 are supported. This driver is currently set up for only FR, but as
|
|
||||||
Sangoma makes more firmware modules available, it can be updated to provide
|
|
||||||
them as well.
|
|
||||||
|
|
||||||
Configuration of the FRAD makes use of another net-tools program, 'fradcfg'.
|
|
||||||
This program makes use of a configuration file (which dlcicfg can also read)
|
|
||||||
to specify the types of boards to be configured as FRADs, as well as perform
|
|
||||||
any board specific configuration. The Sangoma module of fradcfg loads the
|
|
||||||
FR firmware into the card, sets the irq/port/memory information, and provides
|
|
||||||
an initial configuration.
|
|
||||||
|
|
||||||
Additional FRAD device drivers can be added as hardware is available.
|
|
||||||
|
|
||||||
At this time, the dlcicfg and fradcfg programs have not been incorporated into
|
|
||||||
the net-tools distribution. They can be found at ftp.invlogic.com, in
|
|
||||||
/pub/linux. Note that with OS/2 FTPD, you end up in /pub by default, so just
|
|
||||||
use 'cd linux'. v0.10 is for use on pre-2.0.3 and earlier, v0.15 is for
|
|
||||||
pre-2.0.4 and later.

Support for the Frame Relay protocol.
|
|

|
|
||||||
Frame Relay is a fast low-cost way to connect to a remote Internet
|
|
||||||
access provider or to form a private wide area network. The one
|
|
||||||
physical line from your box to the local "switch" (i.e. the entry
|
|
||||||
point to the Frame Relay network, usually at the phone company) can
|
|
||||||
carry several logical point-to-point connections to other computers
|
|
||||||
connected to the Frame Relay network. For a general explanation of
|
|
||||||
the protocol, check out <http://www.mplsforum.org/>.
|
|
||||||
|
|
||||||
To use frame relay, you need supporting hardware (called FRAD) and
|
|
||||||
certain programs from the net-tools package as explained in
