Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Prevent XFRM per-cpu counter updates for one namespace from being
applied to another namespace. Fix from DanS treetman.
2) Fix RCU de-reference in iwl_mvm_get_key_sta_id(), from Johannes
Berg.
3) Remove ethernet header assumption in nft_do_chain_netdev(), from
Pablo Neira Ayuso.
4) Fix cpsw PHY ident with multiple slaves and fixed-phy, from Pascal
Speck.
5) Fix use after free in sixpack_close and mkiss_close.
6) Fix VXLAN fw assertion on bnx2x, from Yuval Mintz.
7) natsemi doesn't check for DMA mapping errors, from Alexey
Khoroshilov.
8) Fix inverted test in ip6addrlbl_get(), from ANdrey Ryabinin.
9) Missing initialization of needed_headroom in geneve tunnel driver,
from Paolo Abeni.
10) Fix conntrack template leak in openvswitch, from Joe Stringer.
11) Mission initialization of wq->flags in sock_alloc_inode(), from
Nicolai Stange.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (35 commits)
sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_close
net, socket, socket_wq: fix missing initialization of flags
drivers: net: cpsw: fix error return code
openvswitch: Fix template leak in error cases.
sctp: label accepted/peeled off sockets
sctp: use GFP_USER for user-controlled kmalloc
qlcnic: fix a loop exit condition better
net: cdc_ncm: avoid changing RX/TX buffers on MTU changes
geneve: initialize needed_headroom
ipv6: honor ifindex in case we receive ll addresses in router advertisements
addrconf: always initialize sysctl table data
ipv6/addrlabel: fix ip6addrlbl_get()
switchdev: bridge: Pass ageing time as clock_t instead of jiffies
sh_eth: fix 16-bit descriptor field access endianness too
veth: don’t modify ip_summed; doing so treats packets with bad checksums as good.
net: usb: cdc_ncm: Adding Dell DW5813 LTE AT&T Mobile Broadband Card
net: usb: cdc_ncm: Adding Dell DW5812 LTE Verizon Mobile Broadband Card
natsemi: add checks for dma mapping errors
rhashtable: Kill harmless RCU warning in rhashtable_walk_init
openvswitch: correct encoding of set tunnel action attributes
