Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix ppp_mppe crypto soft dependencies, from Takashi Iawi. 2) Fix TX completion to be finite, from Sergej Benilov. 3) Use register_pernet_device to avoid a dst leak in tipc, from Xin Long. 4) Double free of TX cleanup in Dirk van der Merwe. 5) Memory leak in packet_set_ring(), from Eric Dumazet. 6) Out of bounds read in qmi_wwan, from Bjørn Mork. 7) Fix iif used in mcast/bcast looped back packets, from Stephen Suryaputra. 8) Fix neighbour resolution on raw ipv6 sockets, from Nicolas Dichtel. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (25 commits) af_packet: Block execution of tasks waiting for transmit to complete in AF_PACKET sctp: change to hold sk after auth shkey is created successfully ipv6: fix neighbour resolution with raw socket ipv6: constify rt6_nexthop() net: dsa: microchip: Use gpiod_set_value_cansleep() net: aquantia: fix vlans not working over bridged network ipv4: reset rt_iif for recirculated mcast/bcast out pkts team: Always enable vlan tx offload net/smc: Fix error path in smc_init net/smc: hold conns_lock before calling smc_lgr_register_conn() bonding: Always enable vlan tx offload net/ipv6: Fix misuse of proc_dointvec "skip_notify_on_dev_down" ipv4: Use return value of inet_iif() for __raw_v4_lookup in the while loop qmi_wwan: Fix out-of-bounds read tipc: check msg->req data len in tipc_nl_compat_bearer_disable net: macb: do not copy the mac address if NULL net/packet: fix memory leak in packet_set_ring() net/tls: fix page double free on TX cleanup net/sched: cbs: Fix error path of cbs_module_init tipc: change to use register_pernet_device ...
