The module will be called uss720.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_SPEEDTCH
This driver provides support for the Alcatel SpeedTouch ADSL USB
modem.
The driver requires the ATM interface and ATM SAR so you need to
enable ATM (under Networking options) and the ATM SAR option. You
will also need PPP over ATM (under Network device support).
This driver is a slightly revised version of Johan Verrept's 1.5
SpeedTouch Driver which has been altered to work on the 2.5 series
kernels.
To use the device you also need a user-mode daemon that downloads
the firmware and (re)initializes the modem. The offical version is
a closed source one from Alcatel that you can get at
<http://www.alcateldsl.com/support.htm>.
A piece of code has recently been sent to linux-usb-devel which
allows the open source user space driver's firmware program
modem_run to be used with this driver instead. You will still
need the Alcatel daemon package to extract the modem firmware from
it (or the windows drivers instead).
For more information, see Johan Verrept's webpages at
<http://linux-usb.sourceforge.net/SpeedTouch/>.

Version 0.2.4A:
- Version for inclusion in 2.5 series kernel
- Modifcations by Richard Purdie (rpurdie@rpsys.net)
- replaced "sarlib" with "atmsar"
- adaptations for inclusion in kernel tree
Version 0.2.4:
- Fixed wrong buffer overrun check in atmsar_decode_rawcell()
reported by Stephen Robinson <stephen.robinson@zen.co.uk>
- Fixed bug when input skb did not contain a multple of 52/53 bytes.
(would happen when the speedtouch device resynced)
also reported by Stephen Robinson <stephen.robinson@zen.co.uk>
Version 0.2.3:
- Fixed wrong allocation size. caused memory corruption in some
cases. Reported by Vladimir Dergachev <volodya@mindspring.com>
- Added some comments
Version 0.2.2:
- Fixed CRCASM (patch from Linus Flannagan <linusf@netservices.eng.net>)
- Fixed problem when user did NOT use the ATMSAR_USE_53BYTE_CELL flag.
(reported by Piers Scannell <email@lot105.com> )
- No more in-buffer rewriting for cloned buffers.
- Removed the PII specific CFLAGS in the Makefile.
Version 0.2.1:
- removed dependancy on alloc_tx. tis presented problems when using
this with the br2684 code.
Version 0.2:
- added AAL0 reassembly
- added alloc_tx support
- replaced alloc_skb in decode functions to dev_alloc_skb to allow
calling from interrupt
- fixed embarassing AAL5 bug. I was setting the pti bit in the wrong
byte...
- fixed another emabrassing bug.. picked up the wrong crc type and
forgot to invert the crc result...
- fixed AAL5 length calculations.
- removed automatic skb freeing from encode functions.
This caused problems because i did kfree_skb it, while it
needed to be popped. I cannot determine though whether it
needs to be popped or not. Figu'e it out ye'self ;-)
- added mru field. This is the buffersize. atmsar_decode_aal0 will
use when it allocates a receive buffer. A stop gap for real
buffer management.
Version 0.1:
- library created.
- only contains AAL5, AAL0 can be easily added. ( actually, only
AAL0 reassembly is missing)

/*
* Driver Module for Alcatel SpeedTouch USB xDSL modem
* Copyright 2001, Alcatel
* Written by Johan Verrept (Johan.Verrept@advalvas.be)
*
1.5A: - Version for inclusion in 2.5 series kernel
- Modifcations by Richard Purdie (rpurdie@rpsys.net)
- made compatible with kernel 2.5.6 onwards by changing
udsl_usb_send_data_context->urb changed to a pointer
and adding code to alloc and free it
- remove_wait_queue() added to udsl_atm_processqueue_thread()
1.5: - fixed memory leak when atmsar_decode_aal5 returned NULL.
(reported by stephen.robinson@zen.co.uk)
1.4: - changed the spin_lock() under interrupt to spin_lock_irqsave()
- unlink all active send urbs of a vcc that is being closed.
1.3.1: - added the version number
1.3: - Added multiple send urb support
- fixed memory leak and vcc->tx_inuse starvation bug
when not enough memory left in vcc.
1.2: - Fixed race condition in udsl_usb_send_data()
1.1: - Turned off packet debugging
