  Modified files:
    sys/compat/linux     linux_ioctl.c linux_ioctl.h 
  Log:
  Deal with a few issues that cropped up following the recent changes
  to the code for translating socket and private ioctls:
  
  - Only perform socket ioctl translation if the file descriptor is a
    socket.
  - Treat socket ioctls on non-sockets specially, and for now assume
    that these are directed at a tap/vmnet device, so translate the
    ioctl numbers as appropriate (the way if_tap abuses some socket
    ioctls to pass non-ifreq data is utterly bogus, but this is how
    VMware on FreeBSD has always "worked"; I will deal with this
    later).
  - Add (untested) support for translating SIOCSIFADDR.
  - In all cases where we fail to translate an ioctl, return ENOIOCTL
    so that other handlers have a chance to do the translation.
  
  This should fix the "/dev/vmnet1: Invalid argument" errors that
  users of VMware were experiencing, though I have only verified this
  on RELENG_4.
