Pull networking fixes from David Miller: 1) Fix null deref in xt_TEE netfilter module, from Eric Dumazet. 2) Several spots need to get to the original listner for SYN-ACK packets, most spots got this ok but some were not. Whilst covering the remaining cases, create a helper to do this. From Eric Dumazet. 3) Missiing check of return value from alloc_netdev() in CAIF SPI code, from Rasmus Villemoes. 4) Don't sleep while != TASK_RUNNING in macvtap, from Vlad Yasevich. 5) Use after free in mvneta driver, from Justin Maggard. 6) Fix race on dst->flags access in dst_release(), from Eric Dumazet. 7) Add missing ZLIB_INFLATE dependency for new qed driver. From Arnd Bergmann. 8) Fix multicast getsockopt deadlock, from WANG Cong. 9) Fix deadlock in btusb, from Kuba Pawlak. 10) Some ipv6_add_dev() failure paths were not cleaning up the SNMP6 counter state. From Sabrina Dubroca. 11) Fix packet_bind() race, which can cause lost notifications, from Francesco Ruggeri. 12) Fix MAC restoration in qlcnic driver during bonding mode changes, from Jarod Wilson. 13) Revert bridging forward delay change which broke libvirt and other userspace things, from Vlad Yasevich. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (65 commits) Revert "bridge: Allow forward delay to be cfgd when STP enabled" bpf_trace: Make dependent on PERF_EVENTS qed: select ZLIB_INFLATE net: fix a race in dst_release() net: mvneta: Fix memory use after free. net: Documentation: Fix default value tcp_limit_output_bytes macvtap: Resolve possible __might_sleep warning in macvtap_do_read() mvneta: add FIXED_PHY dependency net: caif: check return value of alloc_netdev net: hisilicon: NET_VENDOR_HISILICON should depend on HAS_DMA drivers: net: xgene: fix RGMII 10/100Mb mode netfilter: nft_meta: use skb_to_full_sk() helper net_sched: em_meta: use skb_to_full_sk() helper sched: cls_flow: use skb_to_full_sk() helper netfilter: xt_owner: use skb_to_full_sk() helper smack: use skb_to_full_sk() helper net: add skb_to_full_sk() helper and use it in selinux_netlbl_skbuff_setsid() bpf: doc: correct arch list for supported eBPF JIT dwc_eth_qos: Delete an unnecessary check before the function call "of_node_put" bonding: fix panic on non-ARPHRD_ETHER enslave failure ...
