+This is version 029 of the new AX.25 and NET/ROM code for Linux. It
+incorporates many enhancements since the last release, notably the rewriting
+of the connected mode IP code and the IP over NET/ROM code. The opportunity
+has been taken to add the G8BPQ NET/ROM extensions and to add BPQ Ethernet
+support. The latter has been much eased by the use of the new variable
+length header code by Alan Cox.
+
+To use the BPQ Ethernet option, first up the ethernet interface in the usual
+manner, the IP address of the interface is not that important but it will
+be required for the ARP table. Next create an ARP entry in the ARP table of
+type ax25 for the interface binding it to an AX.25 callsign, this callsign
+will be the callsign of that interface. By default BPQ Ethernet uses a
+multi-cast address, this implementation does not, instead the standard
+ethernet broadcast address is used. Therefore the NET.CFG file for the
+ODI driver should look similar to this:
+
+------------------------------ cut here ------------------------------------
+
+LINK SUPPORT
+
+	MAX STACKS 1
+	MAX BOARDS 1
+
+LINK DRIVER E2000			; or other MLID to suit your card
+
+	INT 10				;
+	PORT 300			; to suit your card
+
+	FRAME ETHERNET_II
+
+	PROTOCOL BPQ 8FF ETHERNET_II	; required for BPQ - can change PID
+
+BPQPARMS				; optional - only needed if you want
+					; to override the default target addr
+
+	ETH_ADDR  FF:FF:FF:FF:FF:FF	; Target address
+
+----------------------------- cut here -------------------------------------
+
+The above configuration assumes that only BPQ Ethernet is being used.
+
+It is not possible to run IP over AX.25 on the BPQ Ethernet port. To simply
+route IP frames to (say) eth0 would create standard ethernet IP frames and
+completely bypass the AX.25 code. However it is possible to use IP over
+NET/ROM across a BPQ Ethernet link, the performance of such a system is
+very acceptable indeed.
