[PATCH] USBATM: handle urbs containing partial cells
The receive logic has always assumed that urbs contain an integral
number of ATM cells, which is a bit naughty, though it never caused
any problems with bulk transfers. Isochronous urbs spank us soundly
for this. Fixed thanks to this patch, mostly by Stanislaw Gruszka.

[PATCH] USBATM: allow isochronous transfer
While the usbatm core has had some support for using isoc urbs
for some time, there was no way for users to turn it on. While
use of isoc transfer should still be considered experimental, it
now works well enough to let users turn it on. Minidrivers signal
to the core that they want to use isoc transfer by setting the new
UDSL_USE_ISOC flag. The speedtch minidriver gets a new module
parameter enable_isoc (defaults to false), plus some logic that
checks for the existence of an isoc receive endpoint (not all
speedtouch modems have one).

[PATCH] USBATM: measure buffer size in bytes; force valid sizes
Change the module parameters rcv_buf_size and snd_buf_size to
specify buffer sizes in bytes rather than ATM cells. Since
there is some danger that users may not notice this change,
the parameters are renamed to rcv_buf_bytes etc. The transmit
buffer needs to be a multiple of the ATM cell size in length,
while the receive buffer should be a multiple of the endpoint
maxpacket size (this wasn't enforced before, which causes trouble
with isochronous transfers), so enforce these restrictions. Now
that the usbatm probe method inspects the endpoint maxpacket size,
minidriver bind routines need to set the correct alternate setting
for the interface in their bind routine. This is the reason for
the speedtch changes.

[PATCH] USBATM: shutdown open connections when disconnected
This patch causes vcc_release_async to be applied to any open
vcc's when the modem is disconnected. This signals a socket
shutdown, letting the socket user know that the game is up.
I wrote this patch because of reports that pppd would keep
connections open forever when the modem is disconnected.
This patch does not fix that problem, but it's a step in the
right direction. It doesn't help because the pppoatm module
doesn't yet monitor state changes on the ATM socket, so simply
never realises that the ATM connection has gone down (meaning
it doesn't tell the ppp layer). But at least there is a socket
state change now. Unfortunately this patch may create problems
for those rare users like me who use routed IP or some other
non-ppp connection method that goes via the ATM ARP daemon: the
daemon is buggy, and with this patch will crash when the modem
is disconnected. Users with a buggy atmarpd can simply restart
it after disconnecting the modem.
