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)

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
