we found a bug in net/appletalk/ddp.c concerning broadcast packets. In 
kernel 2.4 it was working fine. The bug first occured 4 years ago when 
switching to new SNAP layer handling. This bug can be splitted up into a 
sending(1) and reception(2) problem:

Sending(1)
In kernel 2.4 broadcast packets were sent to a matching ethernet device 
and atalk_rcv() was called to receive it as "loopback" (so loopback 
packets were shortcutted and handled in DDP layer).

When switching to the new SNAP structure, this shortcut was removed and 
the loopback packet was send to SNAP layer. The author forgot to replace 
the remote device pointer by the loopback device pointer before sending 
the packet to SNAP layer (by calling ddp_dl->request() ) therfor the 
packet was not sent back by underlying layers to ddp's atalk_rcv().

Reception(2)
In atalk_rcv() a packet received by this loopback mechanism contains now 
the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong) 
remote ethernet device pointer) and therefor no matching socket will be 
found to deliver this packet to. Because a broadcast packet should be 
send to the first matching socket (as it is done in many other protocols 
(?)), we removed the network comparison in broadcast case.

Below you will find a patch to correct this bug. Its diffed to kernel 
2.6.14-rc1

Lots of places just needs the states, not even linux/tcp.h, where this
enum was, needs it.

This speeds up development of the refactorings as less sources are
rebuilt when things get moved from net/tcp.h.

Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
