New Revision: 368583
URL: https://svnweb.freebsd.org/changeset/base/368583
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.
