  Modified files:
    sys/netinet          tcp.h tcp_usrreq.c 
  Log:
  Implement parts of the TCP_INFO socket option as found in Linux 2.6.
  This socket option allows processes query a TCP socket for some low
  level transmission details, such as the current send, bandwidth, and
  congestion windows.  Linux provides a 'struct tcpinfo' structure
  containing various variables, rather than separate socket options;
  this makes the API somewhat fragile as it makes it dificult to add
  new entries of interest as requirements and implementation evolve.
  As such, I've included a large pad at the end of the structure.
  Right now, relatively few of the Linux API fields are filled in, and
  some contain no logical equivilent on FreeBSD.  I've include __'d
  entries in the structure to make it easier to figure ou what is and
  isn't omitted.  This API/ABI should be considered unstable for the
  time being.
