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. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (132 commits) igb: Fix for issue where values could be too high for udelay function. i40e: fix null dereference xen-netback: fix gso_prefix check net: make neigh_priv_len in struct net_device 16bit instead of 8bit drivers: net: cpsw: fix for cpsw crash when build as modules xen-netback: napi: don't prematurely request a tx event xen-netback: napi: fix abuse of budget sch_tbf: use do_div() for 64-bit divide udp: ipv4: must add synchronization in udp_sk_rx_dst_set() net:fec: remove duplicate lines in comment about errata ERR006358 Revert "8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature" 8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature xen-netback: make sure skb linear area covers checksum field net: smc91x: Fix device tree based configuration so it's usable udp: ipv4: fix potential use after free in udp_v4_early_demux() macvtap: signal truncated packets tun: unbreak truncated packet signalling net: sched: htb: fix the calculation of quantum net: sched: tbf: fix the calculation of max_size micrel: add support for KSZ8041RNLI ...

[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.
