Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix handling of interrupt status in stmmac driver. Just because we have masked the event from generating interrupts, doesn't mean the bit won't still be set in the interrupt status register. From Alexey Brodkin. 2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha. 3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich. 4) cls_flow does not match on icmpv6 codes properly, from Simon Horman. 5) Initial MAC address can be set incorrectly in some scenerios, from Ivan Vecera. 6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(), from Dan Carpenter. 7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet. 8) Fix crash in iwlwifi when unregistering thermal zone, from Jens Axboe. 9) Check for DMA mapping errors in starfire driver, from Alexey Khoroshilov. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (31 commits) tcp: fix 0 divide in __tcp_select_window() ipv6: pointer math error in ip6_tnl_parse_tlv_enc_lim() net: fix ndo_features_check/ndo_fix_features comment ordering net/sched: matchall: Fix configuration race be2net: fix initial MAC setting ipv6: fix flow labels when the traffic class is non-0 net: thunderx: avoid dereferencing xcv when NULL net/sched: cls_flower: Correct matching on ICMPv6 code ipv6: Paritially checksum full MTU frames net/mlx4_core: Avoid command timeouts during VF driver device shutdown gianfar: synchronize DMA API usage by free_skb_rx_queue w/ gfar_new_page net: ethtool: add support for 2500BaseT and 5000BaseT link modes can: bcm: fix hrtimer/tasklet termination in bcm op removal net: adaptec: starfire: add checks for dma mapping errors net: phy: micrel: KSZ8795 do not set SUPPORTED_[Asym_]Pause can: Fix kernel panic at security_sock_rcv_skb net: macb: Fix 64 bit addressing support for GEM stmmac: Discard masked flags in interrupt status register net/mlx5e: Check ets capability before ets query FW command net/mlx5e: Fix update of hash function/key via ethtool ...
