Log:
  Check TF_TOE not the tod pointer to determine if TOE is active.
  
  The TF_TOE flag is the check used in the rest of the network stack to
  determine if TOE is active on a socket.  There is at least one path in
  the cxgbe(4) TOE driver that can leave the tod pointer non-NULL on a
  socket not using TOE.
