svn commit: r368583 - stable/12/sys/dev/cxgbe/tom

Log:
  MFC 367578: Clear tp->tod in t4_pcb_detach().
  
  Otherwise, a socket can have a non-NULL tp->tod while TF_TOE is clear.
  In particular, if a newly accepted socket falls back to non-TOE due to
  an active open failure, the non-TOE socket will still have tp->tod set
  even though TF_TOE is clear.
