Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Handle stations tied to AP_VLANs properly during mac80211 hw reconfig. From Manikanta Pubbisetty. 2) Fix jump stack depth validation in nf_tables, from Taehee Yoo. 3) Fix quota handling in aRFS flow expiration of mlx5 driver, from Eran Ben Elisha. 4) Exit path handling fix in powerpc64 BPF JIT, from Daniel Borkmann. 5) Use ptr_ring_consume_bh() in page pool code, from Tariq Toukan. 6) Fix cached netdev name leak in nf_tables, from Florian Westphal. 7) Fix memory leaks on chain rename, also from Florian Westphal. 8) Several fixes to DCTCP congestion control ACK handling, from Yuchunk Cheng. 9) Missing rcu_read_unlock() in CAIF protocol code, from Yue Haibing. 10) Fix link local address handling with VRF, from David Ahern. 11) Don't clobber 'err' on a successful call to __skb_linearize() in skb_segment(). From Eric Dumazet. 12) Fix vxlan fdb notification races, from Roopa Prabhu. 13) Hash UDP fragments consistently, from Paolo Abeni. 14) If TCP receives lots of out of order tiny packets, we do really silly stuff. Make the out-of-order queue ending more robust to this kind of behavior, from Eric Dumazet. 15) Don't leak netlink dump state in nf_tables, from Florian Westphal. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (76 commits) net: axienet: Fix double deregister of mdio qmi_wwan: fix interface number for DW5821e production firmware ip: in cmsg IP(V6)_ORIGDSTADDR call pskb_may_pull bnx2x: Fix invalid memory access in rss hash config path. net/mlx4_core: Save the qpn from the input modifier in RST2INIT wrapper r8169: restore previous behavior to accept BIOS WoL settings cfg80211: never ignore user regulatory hint sock: fix sg page frag coalescing in sk_alloc_sg netfilter: nf_tables: move dumper state allocation into ->start tcp: add tcp_ooo_try_coalesce() helper tcp: call tcp_drop() from tcp_data_queue_ofo() tcp: detect malicious patterns in tcp_collapse_ofo_queue() tcp: avoid collapses in tcp_prune_queue() if possible tcp: free batches of packets in tcp_prune_ofo_queue() ip: hash fragments consistently ipv6: use fib6_info_hold_safe() when necessary can: xilinx_can: fix power management handling can: xilinx_can: fix incorrect clear of non-processed interrupts can: xilinx_can: fix RX overflow interrupt not being enabled can: xilinx_can: keep only 1-2 frames in TX FIFO to fix TX accounting ...
