New generic HDLC available

New generic HDLC available

[Krzysztof Halasa]

Hi,

I've put new experimental version of my generic HDLC code on
http://hq.pm.waw.pl/hdlc/ ( ftp://ftp.pm.waw.pl/pub/linux/hdlc/experimental/ )

Currently supported (hw drivers) are C101 and N2 (untested) boards.
Protocols supported:
- X.25 and PPP (via X.25 and syncppp routines)
- Frame Relay (CCITT and ANSI LMI, or no LMI)
- Cisco HDLC
- raw HDLC (you can select NRZ/NRZI/Manchester/FM codes and parity)

This version uses new ioctl interface. Comments welcome.

No HDLC/FR bridging code yet. No Cisco LMI support (for FR) yet.
No docs (except Documentation/networking/generic-hdlc.txt) yet.
I'm thinking about implementing asynchronous HDLC driver.

The patch has been generated against 2.4.4-ac6 tree. It should apply to
pure 2.4.4 as well. Protocol support is now split into separate files
hdlc_fr.c, hdlc_cisco.c etc.

Hi,

Are there any news about the inclusion of these changes in the kernel?

Best regards,

Daniela

I'd like to second the query.  It's additional work I'd rather avoid to
have to track two versions.

Patches don't work with 2.4.9-ac series kernels.
I've put an updated version against 2.4.9-ac10 in
http://www.xyzzy.org.uk/farsync/hdlc-2.4.9-ac10.patch.gz
if you'd like to grab that.

I notice you include patches for existing kernel drivers and since the
farsync driver is now in the 2.4.9 kernel would you like me to supply
you with patches for that ?

I hope so. However, dscc4.c uses the old version. While I think it's
easy to port it to the new one (it should simplify the code in fact),
it has to be done.

So, let´s talk to the maintainer (François Romieu?).  Since your new
patch really improves the current Generic HDLC Layer, it shouldn´t take
too long to be submitted.
