The old, now unused, data structures and SPROM extraction routines
are removed.

Signed-off-by: Larry Finger<Larry.Finger@lwfinger.net>
Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

In disagreement with the SPROM specs, revision 3 devices appear to have
moved the MAC address.

Change ssb to handle the revision 4 SPROM, which is a different size.
This change in size is handled by adding a new variable to the ssb_sprom
struct and using it whenever possible. For those routines that do not
have access to this structure, a 'u16 size' argument is added.

The new PCI_ID for the BCM4328 is also added.

Testing of the Revision 4 SPROM, which is used on the BCM4328, was done
by Michael Gerdau <mgerdau@tiscali.de>.

The SPROM's for various devices utilizing the Sonics Silicon Backplane come
with various revisions. The Revision 2 SPROM inherited the data layout of 1, and
Revision 3 inherited the layout of 2. The first instance of Revision 4 has
now been found in a BCM4328 wireless LAN card. This device does not inherit any
layout from previous versions. Although it was possible to create a data
structure that kept all the old layouts, we decided to start fresh, keep only
those SPROM variables that are used by the drivers that utilize ssb, and to
do the conversion in such a manner that neither compilation or execution will
be affected if a bisection lands in the middle of these changes, while keeping
the patches as small as possible.

In this patch, the sprom structures are changed while maintaining the old ones.

The network namespace pointer can be stored into the dst_ops structure.
This is usefull when there are multiple instances of the dst_ops for a

The garbage collection function receive the dst_ops structure as
parameter. This is useful for the next incoming patchset because it
will need the dst_ops (there will be several instances) and the
network namespace pointer (contained in the dst_ops).

The protocols which do not take care of the namespaces will not be
impacted by this change (expect for the function signature), they do
just ignore the parameter.

arp_ignore has two arguments: dev & in_dev. dev is used for
inet_confirm_addr calling only.

inet_confirm_addr, in turn, either gets in_dev from the device passed

I've no explanation why some unrelated changes seem to occur

I checked the arp_ignore asm and it seems to be due to some
reordered of operation order causing some extra opcodes to be
generated). Still, the benefits are pretty obvious from the
codiff's results.

This is the core. Declare and register the pernet subsys for
addrconf. The init callback the will create the devconf-s.

The init_net will reuse the existing statically declared confs,
so that accessing them from inside the ipv6 code will still
work.

The register_pernet_subsys() is moved above the ipv6_add_dev()
call for loopback, because this function will need the
