Pull networking updates from David Miller: "Highlights: 1) Support TX_RING in AF_PACKET TPACKET_V3 mode, from Sowmini Varadhan. 2) Simplify classifier state on sk_buff in order to shrink it a bit. From Willem de Bruijn. 3) Introduce SIPHASH and it's usage for secure sequence numbers and syncookies. From Jason A. Donenfeld. 4) Reduce CPU usage for ICMP replies we are going to limit or suppress, from Jesper Dangaard Brouer. 5) Introduce Shared Memory Communications socket layer, from Ursula Braun. 6) Add RACK loss detection and allow it to actually trigger fast recovery instead of just assisting after other algorithms have triggered it. From Yuchung Cheng. 7) Add xmit_more and BQL support to mvneta driver, from Simon Guinot. 8) skb_cow_data avoidance in esp4 and esp6, from Steffen Klassert. 9) Export MPLS packet stats via netlink, from Robert Shearman. 10) Significantly improve inet port bind conflict handling, especially when an application is restarted and changes it's setting of reuseport. From Josef Bacik. 11) Implement TX batching in vhost_net, from Jason Wang. 12) Extend the dummy device so that VF (virtual function) features, such as configuration, can be more easily tested. From Phil Sutter. 13) Avoid two atomic ops per page on x86 in bnx2x driver, from Eric Dumazet. 14) Add new bpf MAP, implementing a longest prefix match trie. From Daniel Mack. 15) Packet sample offloading support in mlxsw driver, from Yotam Gigi. 16) Add new aquantia driver, from David VomLehn. 17) Add bpf tracepoints, from Daniel Borkmann. 18) Add support for port mirroring to b53 and bcm_sf2 drivers, from Florian Fainelli. 19) Remove custom busy polling in many drivers, it is done in the core networking since 4.5 times. From Eric Dumazet. 20) Support XDP adjust_head in virtio_net, from John Fastabend. 21) Fix several major holes in neighbour entry confirmation, from Julian Anastasov. 22) Add XDP support to bnxt_en driver, from Michael Chan. 23) VXLAN offloads for enic driver, from Govindarajulu Varadarajan. 24) Add IPVTAP driver (IP-VLAN based tap driver) from Sainath Grandhi. 25) Support GRO in IPSEC protocols, from Steffen Klassert" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1764 commits) Revert "ath10k: Search SMBIOS for OEM board file extension" net: socket: fix recvmmsg not returning error from sock_error bnxt_en: use eth_hw_addr_random() bpf: fix unlocking of jited image when module ronx not set arch: add ARCH_HAS_SET_MEMORY config net: napi_watchdog() can use napi_schedule_irqoff() tcp: Revert "tcp: tcp_probe: use spin_lock_bh()" net/hsr: use eth_hw_addr_random() net: mvpp2: enable building on 64-bit platforms net: mvpp2: switch to build_skb() in the RX path net: mvpp2: simplify MVPP2_PRS_RI_* definitions net: mvpp2: fix indentation of MVPP2_EXT_GLOBAL_CTRL_DEFAULT net: mvpp2: remove unused register definitions net: mvpp2: simplify mvpp2_bm_bufs_add() net: mvpp2: drop useless fields in mvpp2_bm_pool and related code net: mvpp2: remove unused 'tx_skb' field of 'struct mvpp2_tx_queue' net: mvpp2: release reference to txq_cpu[] entry after unmapping net: mvpp2: handle too large value in mvpp2_rx_time_coal_set() net: mvpp2: handle too large value handling in mvpp2_rx_pkts_coal_set() net: mvpp2: remove useless arguments in mvpp2_rx_{pkts, time}_coal_set ...
