Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

Pull networking changes from David Miller:

1) Get rid of the error prone NLA_PUT*() macros that used an embedded
goto.

2) Kill off the token-ring and MCA networking drivers, from Paul
Gortmaker.

3) Reduce high-order allocations made by datagram AF_UNIX sockets, from
Eric Dumazet.

4) Add PTP hardware clock support to IGB and IXGBE, from Richard
Cochran and Jacob Keller.

5) Allow users to query timestamping capabilities of a card via
ethtool, from Richard Cochran.

6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part
of this is that we can now have BPF filters not attached to sockets,
and the loadbalancing function is calculated using one.

7) Francois Romieu went through the network drivers removing gratuitous
uses of netdev->base_addr, perhaps some day we can remove it
completely but it's used for ISA probing still.

8) Add a BPF JIT for sparc. I know, who cares, right? :-)

9) Move networking sysctl registry away from using the compatability
mode interfaces in the sysctl code. From Eric W Biederman.

10) Pavel Emelyanov added a way to save and restore TCP socket state via
TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as
well as a way to forcefully bind a socket to a port via the
sk->sk_reuse value SK_FORCE_REUSE. There is also a
TCP_REPAIR_OPTIONS which allows to reinstante the TCP options
enabled on the connection.

11) Several enhancements from Eric Dumazet that, in particular, can
enhance splice performance on TCP sockets significantly.

a) Reset the offset of the per-socket sendmsg page when we know
we're the only use of the page in linear_to_page().

b) Add facilities such that skb->data can be backed a page rather
than SLAB kmalloc'd memory. In particular devices which were
receiving into linear RX buffers can now end up providing paged
data.

The big result is that code like splice and GRO do not have to copy
any more.

12) Allow a pure sender to more gracefully handle ACK backlogs in TCP.
What can happen at high rates is that the sender hasn't grown his
receive buffer limits at all (he's not receiving data so really
doesn't need to), but the non-data ACKs consume receive buffer
space.

sk_add_backlog() is too aggressive in dropping frames in this case,
so relax it's requirements by using the receive buffer plus the send
buffer limit as the backlog limit instead of just the former.

Also from Eric Dumazet.

13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and
Chris Elston.

14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng.
Basically, we can start fast retransmit before hiting the dupack
threshold under certain conditions.

15) New CODEL active queue management packet scheduler, from Eric
Dumazet based upon initial work by Dave Taht.

Basically, the big feature is that packets are dropped (or ECN bits
are set) based upon how long packets live in the queue, rather than
the queue length (which is what RED uses).

forming the group, they only accept messages from backbone gateways of
the same group.

When multiple backbone gateways relay the same broadcast from the

received broadcasts are recorded and new broadcast packets with
the same content may be dropped if received by another gateway.

batman-adv: add basic bridge loop avoidance code

This second version of the bridge loop avoidance for batman-adv
avoids loops between the mesh and a backbone (usually a LAN).

By connecting multiple batman-adv mesh nodes to the same ethernet
segment a loop can be created when the soft-interface is bridged
into that ethernet segment. A simple visualization of the loop
involving the most common case - a LAN as ethernet segment:

node1 <-- LAN --> node2
| |
wifi <-- mesh --> wifi

Packets from the LAN (e.g. ARP broadcasts) will circle forever from
node1 or node2 over the mesh back into the LAN.

With this patch, batman recognizes backbone gateways, nodes which are
part of the mesh and backbone/LAN at the same time. Each backbone
gateway "claims" clients from within the mesh to handle them
exclusively. By restricting that only responsible backbone gateways
may handle their claimed clients traffic, loops are effectively
avoided.
