Manual merge of rsync://rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git 

This is a fixed-up version of the broken "upstream-2.6.13" branch, where
I re-did the manual merge of drivers/net/r8169.c by hand, and made sure
the history is all good.

Generic HDLC layer
Krzysztof Halasa <khc@pm.waw.pl>
January, 2003
Generic HDLC layer currently supports:
- Frame Relay (ANSI, CCITT and no LMI), with ARP support (no InARP).
Normal (routed) and Ethernet-bridged (Ethernet device emulation)
interfaces can share a single PVC.
- raw HDLC - either IP (IPv4) interface or Ethernet device emulation.
- Cisco HDLC,
- PPP (uses syncppp.c),
- X.25 (uses X.25 routines).

- ARP support (no InARP support in the kernel - there is an
experimental InARP user-space daemon available on:

2. raw HDLC - either IP (IPv4) interface or Ethernet device emulation.
3. Cisco HDLC.

5. X.25 (uses X.25 routines).
There are hardware drivers for the following cards:
- C101 by Moxa Technologies Co., Ltd.
- RISCom/N2 by SDL Communications Inc.
- and others, some not in the official kernel.
Generic HDLC is a protocol driver only - it needs a low-level driver
for your particular hardware.
Ethernet device emulation (using HDLC or Frame-Relay PVC) is compatible
with IEEE 802.1Q (VLANs) and 802.1D (Ethernet bridging).

WAN port. You'll need the "sethdlc" utility, get it from:

Attaching this info to bug reports would be helpful. Anyway, let me know
if you have problems using this.
