      This crashed when an LRO packet generated by bnx2x reached a
      tun device through the bridge.  We're supposed to drop it at
      the bridge.  However, because the check was placed in br_forward
      instead of __br_forward, it's only effective if we are sending
      the packet through a single port.
      
      This patch fixes it by moving the check into __br_forward.

      IPv6: fix to set device name when new IPv6 over IPv6 tunnel device is created. · 20461c17
      Noriaki TAKAMIYA authored
      When the user creates IPv6 over IPv6 tunnel, the device name created
      by the kernel isn't set to t->parm.name, which is referred as the
      result of ioctl().
