Pull networking fixes from David Miller:

 1) Fix negative error code usage in ATM layer, from Stefan Hajnoczi.

 2) If CONFIG_SYSCTL is disabled, the default TTL is not initialized
    properly.  From Ezequiel Garcia.

 3) Missing spinlock init in mvneta driver, from Gregory CLEMENT.

    Long.

 8) Various statistics bug fixes in mlx4 from Eric Dumazet.

 9) Fix some randconfig build errors wrt fou ipv6 from Arnd Bergmann.

10) All of l2tp was namespace aware, but the ipv6 support code was not
    doing so.  From Shmulik Ladkani.

11) Handle on-stack hrtimers properly in pktgen, from Guenter Roeck.

12) Propagate MAC changes properly through VLAN devices, from Mike
    Manning.

13) Fix memory leak in bnx2x_init_one(), from Vitaly Kuznetsov.
