Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking updates and fixes from David Miller: 1) Reinstate the no-ref optimization for input route lookups in ipv4 to fix some routing cache removal perf regressions. 2) Make TCP socket pre-demux work on ipv6 side too, from Eric Dumazet. 3) Get RX hash value from correct place in be2net driver, from Sarveshwar Bandi. 4) Validation of FIB cached routes missing critical check, from Eric Dumazet. 5) EEH support in mlx4 driver, from Kleber Sacilotto de Souza. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (23 commits) ipv6: Early TCP socket demux ipv4: Fix input route performance regression. pch_gbe: vlan skb len fix pch_gbe: add extra clean tx pch_gbe: fix transmit watchdog timeout ixgbe: fix panic while dumping packets on Tx hang with IOMMU be2net: Fix to parse RSS hash from Receive completions correctly. net/mlx4_en: Limit the RFS filter IDs to be < RPS_NO_FILTER hyperv: Add error handling to rndis_filter_device_add() hyperv: Add a check for ring_size value ipv4: rt_cache_valid must check expired routes net/pch_gpe: Cannot disable ethernet autonegation qeth: repair crash in qeth_l3_vlan_rx_kill_vid() netiucv: cleanup attribute usage net: wiznet add missing HAS_IOMEM dependency be2net: Missing byteswap in be_get_fw_log_level causes oops on PowerPC mlx4: Add support for EEH error recovery cdc-ncm: tag Ericsson WWAN devices (eg F5521gw) with FLAG_WWAN wanmain: comparing array with NULL caif: fix NULL pointer check ...
