 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).
-
-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.

 Ethernet device emulation (using HDLC or Frame-Relay PVC) is compatible
 with IEEE 802.1Q (VLANs) and 802.1D (Ethernet bridging).

 Make sure the hdlc.o and the hardware driver are loaded. It should
 create a number of "hdlc" (hdlc0 etc) network devices, one for each
 WAN port. You'll need the "sethdlc" utility, get it from:
