What I don't understand in using SendFile and avoiding the copy to
mbuf's is where does TCP fit in.  We are using tcpip for the web.
When I send a packet, I will eventually, get an acknowledge or I
won't.  I may have to resend a "packet" I sent earlier.  Who worries
about this detail, SendFile or the TCP implementation?
