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

Pull networking fixes from David Miller:

 1) Don't ignore user initiated wireless regulatory settings on cards
    with custom regulatory domains, from Arik Nemtsov.

 2) Fix length check of bluetooth information responses, from Jaganath
    Kanakkassery.

 3) Fix misuse of PTR_ERR in btusb, from Adam Lee.

 4) Handle rfkill properly while iwlwifi devices are offline, from
    Emmanuel Grumbach.

 5) Fix r815x devices DMA'ing to stack buffers, from Hayes Wang.

 6) Kernel info leak in ATM packet scheduler, from Dan Carpenter.

 7) 8139cp doesn't check for DMA mapping errors, from Neil Horman.

 8) Fix bridge multicast code to not snoop when no querier exists,
    otherwise mutlicast traffic is lost.  From Linus Lüssing.

 9) Avoid soft lockups in fib6_run_gc(), from Michal Kubecek.

10) Fix races in automatic address asignment on ipv6, which can result
    in incorrect lifetime assignments.  From Jiri Benc.

11) Cure build bustage when CONFIG_NET_LL_RX_POLL is not set and rename
    it CONFIG_NET_RX_BUSY_POLL to eliminate the last reference to the
    original naming of this feature.  From Cong Wang.

12) Fix crash in TIPC when server socket creation fails, from Ying Xue.

13) macvlan_changelink() silently succeeds when it shouldn't, from
    Michael S Tsirkin.

14) HTB packet scheduler can crash due to sign extension, fix from
    Stephen Hemminger.

15) With the cable unplugged, r8169 prints out a message every 10
    seconds, make it netif_dbg() instead of netif_warn().  From Peter
    Wu.

16) Fix memory leak in rtm_to_ifaddr(), from Daniel Borkmann.

17) sis900 gets spurious TX queue timeouts due to mismanagement of link
    carrier state, from Denis Kirjanov.

18) Validate somaxconn sysctl to make sure it fits inside of a u16.
    From Roman Gushchin.

19) Fix MAC address filtering on qlcnic, from Shahed Shaikh.
