Pull networking fixes from David Miller:

 1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't
    figure out why it breaks things.

 2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it
    was basically doing "x == x", from Dave Jones.

 3) Freescale FEC driver was DMA mapping the wrong number of bytes, from
    Sebastian Siewior.

 4) Blackhole and prohibit routes in ipv6 were not doing the right thing
    because their ->input and ->output methods were not being assigned
    correctly.  Now they behave properly like their ipv4 counterparts.
    From Kamala R.

 5) Several drivers advertise the NETIF_F_FRAGLIST capability, but
    really do not support this feature and will send garbage packets if
    fed fraglist SKBs.  From Eric Dumazet.

 6) Fix long standing user triggerable BUG_ON over loopback in RDS
    protocol stack, from Venkat Venkatsubra.

 7) Several not so common code paths can potentially try to invoke
    packet scheduler actions that might be NULL without checking.  Shore
    things up by either 1) defining a method as mandatory and erroring
    on registration if that method is NULL 2) defininig a method as
    optional and the registration function hooks up a default
    implementation when NULL is seen.  From Jamal Hadi Salim.

 8) Fix fragment detection in xen-natback driver, from Paul Durrant.

 9) Kill dangling enter_memory_pressure method in cg_proto ops, from
    Eric W Biederman.

10) SKBs that traverse namespaces should have their local_df cleared,
    from Hannes Frederic Sowa.

11) IOCB file position is not being updated by macvtap_aio_read() and
    tun_chr_aio_read().  From Zhi Yong Wu.

12) Don't free virtio_net netdev before releasing all of the NAPI
    instances.  From Andrey Vagin.

13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.

14) IPv6 routes that are no cached routes should not count against the
    garbage collection limits.  We had this almost right, but were
    missing handling addrconf generated routes properly.  From Hannes
    Frederic Sowa.

15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL
    route info when they are called, from Stefan Tomanek.

16) TUN and MACVTAP have had truncated packet signalling for some time,
    fix from Jason Wang.

17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet.

18) xen-netback does not interpret the NAPI budget properly for TX work,
    fix from Paul Durrant.

@ -123,6 +123,16 @@ Transmission process is similar to capture as shown below.
[shutdown] close() --------> destruction of the transmission socket and
deallocation of all associated resources.
Socket creation and destruction is also straight forward, and is done
the same way as in capturing described in the previous paragraph:
int fd = socket(PF_PACKET, mode, 0);
The protocol can optionally be 0 in case we only want to transmit
via this socket, which avoids an expensive call to packet_rcv().
In this case, you also need to bind(2) the TX_RING with sll_protocol = 0
set. Otherwise, htons(ETH_P_ALL) or any other protocol, for example.
Binding the socket to your network interface is mandatory (with zero copy) to
know the header size of frames used in the circular buffer.
