Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) The forcedeth conversion from pci_*() DMA interfaces to dma_*() ones missed one spot. From Zhu Yanjun. 2) Missing CRYPTO_SHA256 Kconfig dep in cfg80211, from Johannes Berg. 3) Fix checksum offloading in thunderx driver, from Sunil Goutham. 4) Add SPDX to vm_sockets_diag.h, from Stephen Hemminger. 5) Fix use after free of packet headers in TIPC, from Jon Maloy. 6) "sizeof(ptr)" vs "sizeof(*ptr)" bug in i40e, from Gustavo A R Silva. 7) Tunneling fixes in mlxsw driver, from Petr Machata. 8) Fix crash in fanout_demux_rollover() of AF_PACKET, from Mike Maloney. 9) Fix race in AF_PACKET bind() vs. NETDEV_UP notifier, from Eric Dumazet. 10) Fix regression in sch_sfq.c due to one of the timer_setup() conversions. From Paolo Abeni. 11) SCTP does list_for_each_entry() using wrong struct member, fix from Xin Long. 12) Don't use big endian netlink attribute read for IFLA_BOND_AD_ACTOR_SYSTEM, it is in cpu endianness. Also from Xin Long. 13) Fix mis-initialization of q->link.clock in CBQ scheduler, preventing adding filters there. From Jiri Pirko. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (67 commits) ethernet: dwmac-stm32: Fix copyright net: via: via-rhine: use %p to format void * address instead of %x net: ethernet: xilinx: Mark XILINX_LL_TEMAC broken on 64-bit myri10ge: Update MAINTAINERS net: sched: cbq: create block for q->link.block atm: suni: remove extraneous space to fix indentation atm: lanai: use %p to format kernel addresses instead of %x VSOCK: Don't set sk_state to TCP_CLOSE before testing it atm: fore200e: use %pK to format kernel addresses instead of %x ambassador: fix incorrect indentation of assignment statement vxlan: use __be32 type for the param vni in __vxlan_fdb_delete bonding: use nla_get_u64 to extract the value for IFLA_BOND_AD_ACTOR_SYSTEM sctp: use right member as the param of list_for_each_entry sch_sfq: fix null pointer dereference at timer expiration cls_bpf: don't decrement net's refcount when offload fails net/packet: fix a race in packet_bind() and packet_notifier() packet: fix crash in fanout_demux_rollover() sctp: remove extern from stream sched sctp: force the params with right types for sctp csum apis sctp: force SCTP_ERROR_INV_STRM with __u32 when calling sctp_chunk_fail ...
