Pull networking fixes from David Miller: 1) Fix ARM BPF JIT handling of negative 'k' values, from Chen Gang. 2) Insufficient space reserved for bridge netlink values, fix from Stephen Hemminger. 3) Some dst_neigh_lookup*() callers don't interpret error pointer correctly, fix from Zhouyi Zhou. 4) Fix transport match in SCTP active_path loops, from Xugeng Zhang. 5) Fix qeth driver handling of multi-order SKB frags, from Frank Blaschka. 6) fec driver is missing napi_disable() call, resulting in crashes on unload, from Georg Hofmann. 7) Don't try to handle PMTU events on a listening socket, fix from Eric Dumazet. 8) Fix timestamp location calculations in IP option processing, from David Ward. 9) FIB_TABLE_HASHSZ setting is not controlled by the correct kconfig tests, from Denis V Lunev. 10) Fix TX descriptor push handling in SFC driver, from Ben Hutchings. 11) Fix isdn/hisax and tulip/de4x5 kconfig dependencies, from Arnd Bergmann. 12) bnx2x statistics don't handle 4GB rollover correctly, fix from Maciej Żenczykowski. 13) Openvswitch bug fixes for vport del/new error reporting, missing genlmsg_end() call in netlink processing, and mis-parsing of LLC/SNAP ethernet types. From Rich Lane. 14) SKB pfmemalloc state should only be propagated from the head page of a compound page, fix from Pavel Emelyanov. 15) Fix link handling in tg3 driver for 5715 chips when autonegotation is disabled. From Nithin Sujir. 16) Fix inverted test of cpdma_check_free_tx_desc return value in davinci_emac driver, from Mugunthan V N. 17) vlan_depth is incorrectly calculated in skb_network_protocol(), from Li RongQing. 18) Fix probing of Gobi 1K devices in qmi_wwan driver, and fix NCM device mode backwards compat in cdc_ncm driver. From Bjørn Mork. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (52 commits) inet: limit length of fragment queue hash table bucket lists qeth: Fix scatter-gather regression qeth: Fix invalid router settings handling qeth: delay feature trace tcp: dont handle MTU reduction on LISTEN socket bnx2x: fix occasional statistics off-by-4GB error vhost/net: fix heads usage of ubuf_info bridge: Add support for setting BR_ROOT_BLOCK flag. bnx2x: add missing napi deletion in error path drivers: net: ethernet: ti: davinci_emac: fix usage of cpdma_check_free_tx_desc() ethernet/tulip: DE4x5 needs VIRT_TO_BUS isdn: hisax: netjet requires VIRT_TO_BUS net: cdc_ncm, cdc_mbim: allow user to prefer NCM for backwards compatibility rtnetlink: Mask the rta_type when range checking Revert "ip_gre: make ipgre_tunnel_xmit() not parse network header as IP unconditionally" Fix dst_neigh_lookup/dst_neigh_lookup_skb return value handling bug smsc75xx: configuration help incorrectly mentions smsc95xx net: fec: fix missing napi_disable call net: fec: restart the FEC when PHY speed changes skb: Propagate pfmemalloc on skb from head page only ...
