It is essential that TCP connections be able to survive link failures.  If you
don't have this, you basically have to re-implement much of TCP at a higher
layer.  (Typically, explicit acks for application data, the ability to detect
a lack of acknowledgment and to retransmit unacknowledged application data,
and to gracefully handle duplicate transmissions of application data.)
