Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking updates from David Miller: 1) Fix flexcan build on big endian, from Arnd Bergmann 2) Correctly attach cpsw to GPIO bitbang MDIO drive, from Stefan Roese 3) udp_add_offload has to use GFP_ATOMIC since it can be invoked from non-sleepable contexts. From Or Gerlitz 4) vxlan_gro_receive() does not iterate over all possible flows properly, fix also from Or Gerlitz 5) CAN core doesn't use a proper SKB destructor when it hooks up sockets to SKBs. Fix from Oliver Hartkopp 6) ip_tunnel_xmit() can use an uninitialized route pointer, fix from Eric Dumazet 7) Fix address family assignment in IPVS, from Michal Kubecek 8) Fix ath9k build on ARM, from Sujith Manoharan 9) Make sure fail_over_mac only applies for the correct bonding modes, from Ding Tianhong 10) The udp offload code doesn't use RCU correctly, from Shlomo Pongratz 11) Handle gigabit features properly in generic PHY code, from Florian Fainelli 12) Don't blindly invoke link operations in rtnl_link_get_slave_info_data_size, they are optional. Fix from Fernando Luis Vazquez Cao 13) Add USB IDs for Netgear Aircard 340U, from Bjørn Mork 14) Handle netlink packet padding properly in openvswitch, from Thomas Graf 15) Fix oops when deleting chains in nf_tables, from Patrick McHardy 16) Fix RX stalls in xen-netback driver, from Zoltan Kiss 17) Fix deadlock in mac80211 stack, from Emmanuel Grumbach 18) inet_nlmsg_size() forgets to consider ifa_cacheinfo, fix from Geert Uytterhoeven 19) tg3_change_mtu() can deadlock, fix from Nithin Sujir 20) Fix regression in setting SCTP local source addresses on accepted sockets, caused by some generic ipv6 socket changes. Fix from Matija Glavinic Pecotic 21) IPPROTO_* must be pure defines, otherwise module aliases don't get constructed properly. Fix from Jan Moskyto 22) IPV6 netconsole setup doesn't work properly unless an explicit source address is specified, fix from Sabrina Dubroca 23) Use __GFP_NORETRY for high order skb page allocations in sock_alloc_send_pskb and skb_page_frag_refill. From Eric Dumazet 24) Fix a regression added in netconsole over bridging, from Cong Wang 25) TCP uses an artificial offset of 1ms for SRTT, but this doesn't jive well with TCP pacing which needs the SRTT to be accurate. Fix from Eric Dumazet 26) Several cases of missing header file includes from Rashika Kheria 27) Add ZTE MF667 device ID to qmi_wwan driver, from Raymond Wanyoike 28) TCP Small Queues doesn't handle nonagle properly in some corner cases, fix from Eric Dumazet 29) Remove extraneous read_unlock in bond_enslave, whoops. From Ding Tianhong 30) Fix 9p trans_virtio handling of vmalloc buffers, from Richard Yao * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (136 commits) 6lowpan: fix lockdep splats alx: add missing stats_lock spinlock init 9p/trans_virtio.c: Fix broken zero-copy on vmalloc() buffers bonding: remove unwanted bond lock for enslave processing USB2NET : SR9800 : One chip USB2.0 USB2NET SR9800 Device Driver Support tcp: tsq: fix nonagle handling bridge: Prevent possible race condition in br_fdb_change_mac_address bridge: Properly check if local fdb entry can be deleted when deleting vlan bridge: Properly check if local fdb entry can be deleted in br_fdb_delete_by_port bridge: Properly check if local fdb entry can be deleted in br_fdb_change_mac_address bridge: Fix the way to check if a local fdb entry can be deleted bridge: Change local fdb entries whenever mac address of bridge device changes bridge: Fix the way to find old local fdb entries in br_fdb_change_mac_address bridge: Fix the way to insert new local fdb entries in br_fdb_changeaddr bridge: Fix the way to find old local fdb entries in br_fdb_changeaddr tcp: correct code comment stating 3 min timeout for FIN_WAIT2, we only do 1 min net: vxge: Remove unused device pointer net: qmi_wwan: add ZTE MF667 3c59x: Remove unused pointer in vortex_eisa_cleanup() net: fix 'ip rule' iif/oif device rename ...

301 Say Y if you want to use one of the following 100Mbps USB Ethernet
302 device based on the CoreChip-sz SR9800 chip.
303
304 This driver makes the adapter appear as a normal Ethernet interface,
305 typically on eth0, if it is the only ethernet device, or perhaps on
306 eth1, if you have a PCI or ISA ethernet card installed.

309 module will be called sr9800.
