Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1745 commits) dp83640: free packet queues on remove dp83640: use proper function to free transmit time stamping packets ipv6: Do not use routes from locally generated RAs |PATCH net-next] tg3: add tx_dropped counter be2net: don't create multiple RX/TX rings in multi channel mode be2net: don't create multiple TXQs in BE2 be2net: refactor VF setup/teardown code into be_vf_setup/clear() be2net: add vlan/rx-mode/flow-control config to be_setup() net_sched: cls_flow: use skb_header_pointer() ipv4: avoid useless call of the function check_peer_pmtu TCP: remove TCP_DEBUG net: Fix driver name for mdio-gpio.c ipv4: tcp: fix TOS value in ACK messages sent from TIME_WAIT rtnetlink: Add missing manual netlink notification in dev_change_net_namespaces ipv4: fix ipsec forward performance regression jme: fix irq storm after suspend/resume route: fix ICMP redirect validation net: hold sock reference while processing tx timestamps tcp: md5: add more const attributes Add ethtool -g support to virtio_net ... Fix up conflicts in: - drivers/net/Kconfig: The split-up generated a trivial conflict with removal of a stale reference to Documentation/networking/net-modules.txt. Remove it from the new location instead. - fs/sysfs/dir.c: Fairly nasty conflicts with the sysfs rb-tree usage, conflicting with Eric Biederman's changes for tagged directories.
