Fixed tun/tap driver's handling of hw addresses.  The hw address is stored
in both the net_device.dev_addr and tun.dev_addr fields.  These fields were
not kept synchronized, and in fact weren't even initialized to the same
value.  Now during both init and when performing SIOCSIFHWADDR on the tun
device these values are both updated.  However, if SIOCSIFHWADDR is
performed on the net device directly (for instance, setting the hw address
using ifconfig), the tun device does not get updated.  Perhaps the
tun.dev_addr field should be removed completely at some point, as it is
redundant and net_device.dev_addr can be used anywhere it is used.

I noticed recently that, in skb_checksum(), "offset" and "start" are
essentially the same thing and have the same value throughout the
function, despite being computed differently. Using a single variable
allows some cleanups and makes the skb_checksum() function smaller,
more readable, and presumably marginally faster.

We appear to have many other "sk_buff walker" functions built on the
exact same model, so the cleanup applies to them, too. Here is a list
of the functions I found to be affected:

net/appletalk/ddp.c:atalk_sum_skb()
net/core/datagram.c:skb_copy_datagram_iovec()
net/core/datagram.c:skb_copy_and_csum_datagram()
net/core/skbuff.c:skb_copy_bits()
net/core/skbuff.c:skb_store_bits()
net/core/skbuff.c:skb_checksum()
net/core/skbuff.c:skb_copy_and_csum_bit()
net/core/user_dma.c:dma_skb_copy_datagram_iovec()
net/xfrm/xfrm_algo.c:skb_icv_walk()
net/xfrm/xfrm_algo.c:skb_to_sgvec()

OTOH, I admit I'm a bit surprised, the cleanup is rather obvious so I'm
really wondering if I am missing something. Can anyone please comment
on this?

On a system with a lot of SAs, counting SAD entries chews useful
CPU time since you need to dump the whole SAD to user space;
i.e something like ip xfrm state ls | grep -i src | wc -l
I have seen taking literally minutes on a 40K SAs when the system
is swapping.
With this patch, some of the SAD info (that was already being tracked)
is exposed to user space. i.e you do:
ip xfrm state count
And you get the count; you can also pass -s to the command line and
get the hash info.

If a bridge is not running STP, then it has no way to detect a cycle
in the network. But if it is not running STP and some other machine
or device is running STP, then if STP BPDU's get forwarded to it can
detect the cycle.

The change to forward STP bpdu's (for usermode STP) through normal path,
changed the packet type in the process. Since link local stuff is multicast, it
should stay pkt_type = PACKET_MULTICAST.  The code was probably copy/pasted
incorrectly from the bridge pseudo-device receive path.

This patch moves the non-proc SNMP code into addrconf.c and reuses
IPv4 SNMP code where applicable.

As a result we can skip proc.o if /proc is disabled.

used by addrconf.c for now.  If they ever get used elsewhere we can
always remove the static.

This patch makes two enhancements to msg_set_bits():

1) It now ignores any bits of the new field value that are not
   covered by the mask being used.  (Previously, if the new value
   exceeded the size of the mask the extra bits could corrupt
   other fields in the message header word being updated.)

2) The code has been optimized to minimize the number of run-time
   endianness conversion operations by leveraging the fact that the
   mask (and, in some cases, the value as well) is constant and the
   necessary conversion can be performed by the compiler.
