If the association has been restarted, we need to reset the
transport congestion variables as well as accumulated error
counts and CACC variables.  If we do not, the association
will use the wrong values and may terminate prematurely.

This was found with a scenario where the peer restarted
the association when lksctp was in the last HB timeout for
its association.  The restart happened, but the error counts
have not been reset and when the timeout occurred, a newly
restarted association was terminated due to excessive
retransmits.

2960bis states (Section 8.3):

   D) Request an on-demand HEARTBEAT on a specific destination transport
      address of a given association.

   The endpoint should increment the respective error counter of the
   destination transport address each time a HEARTBEAT is sent to that
   address and not acknowledged within one RTO.

During association restart we may have stale data sitting
on the ULP queue waiting for ordering or reassembly.  This
data may cause severe problems if not cleaned up.  In particular
stale data pending ordering may cause problems with receive
window exhaustion if our peer has decided to restart the
association.

The manual says that it is required and we actually have crash reports
where loads see stale data due to not having membars here.

In one case the networking does:

	memset(skb, 0, offsetof(struct sk_buff, truesize));

and then some code later checks skb->nohdr for zero, but it's still
the value that was there before the memset().

Note that arch/sparc64/lib/xor.S already got this right.

This patch (as872) adds a device table entry and a new quirk flag to
the usblp driver for the Seiko Epson Receipt printer.  This printer
returns Vendor-Specific values for bInterfaceClass and
bInterfaceSubClass, but the bInterfaceProtocol value is valid and it
works with usblp.  The new quirks flag tells the driver to ignore the
Class and SubClass values in the interface descriptor.

Add an ID to recognise the Novatel EV620 wireless adapter.
http://www.novatelwireless.com/products/expedite/ev620.html

It looks like a mini PCI-Express adapter.  The mPCIE connector includes USB
pins... the card shows up to the system as a USB device, and powers itself
from the PCI bus.

The card I have isn't activated yet, so I can't get a PPP session up yet, but
I have tested basic serial communication successfully in both 2.6.18 and
2.6.20 kernels, once the product ID was added.  (the driver changed quite a
bit between the two revs.)  In both drivers, it responds to AT commands and
such.

these devices have a shared interrupt endpoint. For serialcore to pass
an interrupt endpoint to a subdriver, the subdriver must define and
_export_ a fitting callback. The mos7720 driver failed to do so. This led
invariably to an oops upon open. This patch fixes it. The driver is useless
without it. Please try to get this into 2.6.21 and the stable kernels that
have this driver.
