Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "Just the usual assortment of small'ish fixes: 1) Conntrack timeout is sometimes not initialized properly, from Alexander Potapenko. 2) Add a reasonable range limit to tcp_min_rtt_wlen to avoid undefined behavior. From ZhangXiaoxu. 3) des1 field of descriptor in stmmac driver is initialized with the wrong variable. From Yue Haibing. 4) Increase mlxsw pci sw reset timeout a little bit more, from Ido Schimmel. 5) Match IOT2000 stmmac devices more accurately, from Su Bao Cheng. 6) Fallback refcount fix in TLS code, from Jakub Kicinski. 7) Fix max MTU check when using XDP in mlx5, from Maxim Mikityanskiy. 8) Fix recursive locking in team driver, from Hangbin Liu. 9) Fix tls_set_device_offload_Rx() deadlock, from Jakub Kicinski. 10) Don't use napi_alloc_frag() outside of softiq context of socionext driver, from Ilias Apalodimas. 11) MAC address increment overflow in ncsi, from Tao Ren. 12) Fix a regression in 8K/1M pool switching of RDS, from Zhu Yanjun. 13) ipv4_link_failure has to validate the headers that are actually there because RAW sockets can pass in arbitrary garbage, from Eric Dumazet" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (43 commits) ipv4: add sanity checks in ipv4_link_failure() net/rose: fix unbound loop in rose_loopback_timer() rxrpc: fix race condition in rxrpc_input_packet() net: rds: exchange of 8K and 1M pool net: vrf: Fix operation not supported when set vrf mac net/ncsi: handle overflow when incrementing mac address net: socionext: replace napi_alloc_frag with the netdev variant on init net: atheros: fix spelling mistake "underun" -> "underrun" spi: ST ST95HF NFC: declare missing of table spi: Micrel eth switch: declare missing of table net: stmmac: move stmmac_check_ether_addr() to driver probe netfilter: fix nf_l4proto_log_invalid to log invalid packets netfilter: never get/set skb->tstamp netfilter: ebtables: CONFIG_COMPAT: drop a bogus WARN_ON Documentation: decnet: remove reference to CONFIG_DECNET_ROUTE_FWMARK dt-bindings: add an explanation for internal phy-mode net/tls: don't leak IV and record seq when offload fails net/tls: avoid potential deadlock in tls_set_device_offload_rx() selftests/net: correct the return value for run_afpackettests team: fix possible recursive locking when add slaves ...
