Unfortunately, we don’t support any of those options at this time. In particular, the stack won’t delay segments and tcp doesn’t do keepalives. Do you really need those?
If you need to constrain tcp mss, you can indirectly do it by configuring the tcp mtu as a vpp startup parameter. You can’t do it per connection at this time.
