Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "This looks like a lot but it's a mixture of regression fixes as well as fixes for longer standing issues. 1) Fix on-channel cancellation in mac80211, from Johannes Berg. 2) Handle CHECKSUM_COMPLETE properly in xt_TCPMSS netfilter xtables module, from Eric Dumazet. 3) Avoid infinite loop in UDP SO_REUSEPORT logic, also from Eric Dumazet. 4) Avoid a NULL deref if we try to set SO_REUSEPORT after a socket is bound, from Craig Gallek. 5) GRO key comparisons don't take lightweight tunnels into account, from Jesse Gross. 6) Fix struct pid leak via SCM credentials in AF_UNIX, from Eric Dumazet. 7) We need to set the rtnl_link_ops of ipv6 SIT tunnels before we register them, otherwise the NEWLINK netlink message is missing the proper attributes. From Thadeu Lima de Souza Cascardo. 8) Several Spectrum chip bug fixes for mlxsw switch driver, from Ido Schimmel 9) Handle fragments properly in ipv4 easly socket demux, from Eric Dumazet. 10) Don't ignore the ifindex key specifier on ipv6 output route lookups, from Paolo Abeni" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (128 commits) tcp: avoid cwnd undo after receiving ECN irda: fix a potential use-after-free in ircomm_param_request net: tg3: avoid uninitialized variable warning net: nb8800: avoid uninitialized variable warning net: vxge: avoid unused function warnings net: bgmac: clarify CONFIG_BCMA dependency net: hp100: remove unnecessary #ifdefs net: davinci_cpdma: use dma_addr_t for DMA address ipv6/udp: use sticky pktinfo egress ifindex on connect() ipv6: enforce flowi6_oif usage in ip6_dst_lookup_tail() netlink: not trim skb for mmaped socket when dump vxlan: fix a out of bounds access in __vxlan_find_mac net: dsa: mv88e6xxx: fix port VLAN maps fib_trie: Fix shift by 32 in fib_table_lookup net: moxart: use correct accessors for DMA memory ipv4: ipconfig: avoid unused ic_proto_used symbol bnxt_en: Fix crash in bnxt_free_tx_skbs() during tx timeout. bnxt_en: Exclude rx_drop_pkts hw counter from the stack's rx_dropped counter. bnxt_en: Ring free response from close path should use completion ring net_sched: drr: check for NULL pointer in drr_dequeue ...
