Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "A quick set of bug fixes after there initial networking merge: 1) Netlink multicast group storage allocator only was tested with nr_groups equal to 1, make it work for other values too. From Matti Vaittinen. 2) Check build_skb() return value in macb and hip04_eth drivers, from Weidong Wang. 3) Don't leak x25_asy on x25_asy_open() failure. 4) More DMA map/unmap fixes in 3c59x from Neil Horman. 5) Don't clobber IP skb control block during GSO segmentation, from Konstantin Khlebnikov. 6) ECN helpers for ipv6 don't fixup the checksum, from Eric Dumazet. 7) Fix SKB segment utilization estimation in xen-netback, from David Vrabel. 8) Fix lockdep splat in bridge addrlist handling, from Nikolay Aleksandrov" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (26 commits) bgmac: Fix reversed test of build_skb() return value. bridge: fix lockdep addr_list_lock false positive splat net: smsc: Add support h8300 xen-netback: free queues after freeing the net device xen-netback: delete NAPI instance when queue fails to initialize xen-netback: use skb to determine number of required guest Rx requests net: sctp: Move sequence start handling into sctp_transport_get_idx() ipv6: update skb->csum when CE mark is propagated net: phy: turn carrier off on phy attach net: macb: clear interrupts when disabling them sctp: support to lookup with ep+paddr in transport rhashtable net: hns: fixes no syscon error when init mdio dts: hisi: fixes no syscon fault when init mdio net: preserve IP control block during GSO segmentation fsl/fman: Delete one function call "put_device" in dtsec_config() hip04_eth: fix missing error handle for build_skb failed 3c59x: fix another page map/single unmap imbalance 3c59x: balance page maps and unmaps x25_asy: Free x25_asy on x25_asy_open() failure. mlxsw: fix SWITCHDEV_OBJ_ID_PORT_MDB ...
