Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:

 1) Fix stack allocation in s390 BPF JIT, from Michael Holzheu.

 2) Disable LRO on openvswitch paths, from Jiri Benc.

 3) UDP early demux doesn't handle multicast group membership properly,
    fix from Shawn Bohrer.

 4) Fix TX queue hang due to incorrect handling of mixed sized fragments
    and linearlization in i40e driver, from Anjali Singhai Jain.

 5) Cannot use disable_irq() in timer handler of AMD xgbe driver, from
    Thomas Lendacky.

 6) b2net driver improperly assumes pci_alloc_consistent() gives zero'd
    out memory, use dma_zalloc_coherent().  From Sriharsha Basavapatna.

 7) Fix use-after-free in MPLS and ipv6, from Robert Shearman.

 8) Missing neif_napi_del() calls in cleanup paths of b44 driver, from
    Hauke Mehrtens.
