Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) If the local_df boolean is set on an SKB we have to allocate a unique ID even if IP_DF is set in the ipv4 headers, from Ansis Atteka. 2) Some fixups for the new chipset support that went into the sfc driver, from Ben Hutchings. 3) Because SCTP bypasses a good chunk of, and actually duplicates, the logic of the ipv6 output path, some IPSEC things don't get done properly. Integrate SCTP better into the ipv6 output path so that these problems are fixed and such issues don't get missed in the future either. From Daniel Borkmann. 4) Fix skge regressions added by the DMA mapping error return checking added in v3.10, from Mikulas Patocka. 5) Kill some more IRQF_DISABLED references, from Michael Opdenacker. 6) Fix races and deadlocks in the bridging code, from Hong Zhiguo. 7) Fix error handling in tun_set_iff(), in particular don't leak resources. From Jason Wang. 8) Prevent format-string injection into xen-netback driver, from Kees Cook. 9) Fix regression added to netpoll ARP packet handling, in particular check for the right ETH_P_ARP protocol code. From Sonic Zhang. 10) Try to deal with AMD IOMMU errors when using r8169 chips, from Francois Romieu. 11) Cure freezes due to recent changes in the rt2x00 wireless driver, from Stanislaw Gruszka. 12) Don't do SPI transfers (which can sleep) in interrupt context in cw1200 driver, from Solomon Peachy. 13) Fix LEDs handling bug in 5720 tg3 chips already handled for 5719. From Nithin Sujir. 14) Make xen_netbk_count_skb_slots() count the actual number of slots that will be used, taking into consideration packing and other issues that the transmit path will run into. From David Vrabel. 15) Use the correct maximum age when calculating the bridge message_age_timer, from Chris Healy. 16) Get rid of memory leaks in mcs7780 IRDA driver, from Alexey Khoroshilov. 17) Netfilter conntrack extensions were converted to RCU but are not always freed properly using kfree_rcu(). Fix from Michal Kubecek. 18) VF reset recovery not being done correctly in qlcnic driver, from Manish Chopra. 19) Fix inverted test in ATM nicstar driver, from Andy Shevchenko. 20) Missing workqueue destroy in cxgb4 error handling, from Wei Yang. 21) Internal switch not initialized properly in bgmac driver, from Rafał Miłecki. 22) Netlink messages report wrong local and remote addresses in IPv6 tunneling, from Ding Zhi. 23) ICMP redirects should not generate socket errors in DCCP and SCTP. We're still working out how this should be handled for RAW and UDP sockets. From Daniel Borkmann and Duan Jiong. 24) We've had several bugs wherein the network namespace's loopback device gets accessed after it is free'd, NULL it out so that we can catch these problems more readily. From Eric W Biederman. 25) Fix regression in TCP RTO calculations, from Neal Cardwell. 26) Fix too early free of xen-netback network device when VIFs still exist. From Paul Durrant. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (87 commits) netconsole: fix a deadlock with rtnl and netconsole's mutex netpoll: fix NULL pointer dereference in netpoll_cleanup skge: fix broken driver ip: generate unique IP identificator if local fragmentation is allowed ip: use ip_hdr() in __ip_make_skb() to retrieve IP header xen-netback: Don't destroy the netdev until the vif is shut down net:dccp: do not report ICMP redirects to user space cnic: Fix crash in cnic_bnx2x_service_kcq() bnx2x, cnic, bnx2i, bnx2fc: Fix bnx2i and bnx2fc regressions. vxlan: Avoid creating fdb entry with NULL destination tcp: fix RTO calculated from cached RTT drivers: net: phy: cicada.c: clears warning Use #include <linux/io.h> instead of <asm/io.h> net loopback: Set loopback_dev to NULL when freed batman-adv: set the TAG flag for the vid passed to BLA netfilter: nfnetlink_queue: use network skb for sequence adjustment net: sctp: rfc4443: do not report ICMP redirects to user space net: usb: cdc_ether: use usb.h macros whenever possible net: usb: cdc_ether: fix checkpatch errors and warnings net: usb: cdc_ether: Use wwan interface for Telit modules ip6_tunnels: raddr and laddr are inverted in nl msg ...
