ipmr: advertise new mfc entries via rtnl
This patch allows to monitor mfc activities via rtnetlink.
To avoid parsing two times the mfc oifs, we use maxvif to allocate the rtnl
msg, thus we may allocate some superfluous space.

ipmr/ip6mr: allow to get unresolved cache via netlink
/proc/net/ip[6]_mr_cache allows to get all mfc entries, even if they are put in
the unresolved list (mfc[6]_unres_queue). But only the table RT_TABLE_DEFAULT is
displayed.
This patch adds the parsing of the unresolved list when the dump is made via
rtnetlink, hence each table can be checked.
In IPv6, we set rtm_type in ip6mr_fill_mroute(), because in case of unresolved
mfc __ip6mr_fill_mroute() will not set it. In IPv4, it is already done.

* Two patches two improve ct object traceability. Now ct objects are

This patch adds the ptp_caps structure, ptp api implementation,

Frequency adjustment is performed using hardware with a 24 bit
accumulator and a programmable correction value. On each clk, the
correction value gets added to the accumulator and when it overflows,
the time counter is incremented/decremented and the accumulator reset.
So conversion from ppb to correction value is
ppb * (1 << 24) / 1000000000

Networking: Remove __dev* markings from the networking drivers
This is a series of patches that remove the dev* attributes for all
networking drivers, with the exception of wireless drivers, those are in
a different branch.
Use of __devinit, __devexit_p, __devinitdata, __devinitconst, and
__devexit are no longer needed since CONFIG_HOTPLUG is being removed as
an option.
Note, there are some devinit compiler section mismatch warnings due to
this series, but they are fixed up when merged with my driver-next
branch, which fixes the PCI device id warnings, and removes the modpost
detection, as it's no longer needed.

ipv6: Fix default route failover when CONFIG_IPV6_ROUTER_PREF=n
I believe this commit from 2008 was incorrect:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=398bcbebb6f721ac308df1e3d658c0029bb74503
When CONFIG_IPV6_ROUTER_PREF is disabled, the kernel should follow
RFC4861 section 6.3.6: if no route is NUD_VALID, then traffic should be
sprayed across all routers (indirectly triggering NUD) until one of them
becomes NUD_VALID.
However, the following experiment demonstrates that this does not work:
1) Connect to an IPv6 network.
2) Change the router's MAC (and link-local) address.
The kernel will lock onto the first router and never try the new one, even
if the first becomes unreachable. This patch fixes the problem by
allowing rt6_check_neigh() to return 0; if all routers return 0, then
rt6_select() will fall back to round-robin behavior.
This patch should have no effect when CONFIG_IPV6_ROUTER_PREF=y.
Note that rt6_check_neigh() is only used in a boolean context, so I've
changed its return type accordingly.

Historically tun supported two modes of operation:
- in default mode, a small number of packets would get queued
at the device, the rest would be queued in qdisc
- in one queue mode, all packets would get queued at the device
This might have made sense up to a point where we made the
queue depth for both modes the same and set it to
a huge value (500) so unless the consumer
is stuck the chance of losing packets is small.
Thus in practice both modes behave the same, but the
default mode has some problems:
- if packets are never consumed, fragments are never orphaned
which cases a DOS for sender using zero copy transmit
- overrun errors are hard to diagnose: fifo error is incremented
only once so you can not distinguish between
userspace that is stuck and a transient failure,
tcpdump on the device does not show any traffic
Userspace solves this simply by enabling IFF_ONE_QUEUE
but there seems to be little point in not doing the
right thing for everyone, by default.
