ip_statistics bug in Linux 2.0/2.2/2.3 TCP?

[Neal Cardwell <neal@xxxxxxxxx>]

tcp_v4_do_rcv() seems to be missing a counter bump like:

  ip_statistics.IpInDelivers++;

The analogous counter increment is in tcp_v6_do_rcv(), which is one reason
i suspect this is a bug. Another reason is the very large discrepancy
between IpInReceives and IpInDelivers when there is a lot of inbound TCP
traffic; this seems counterintuitive, at the very least. Is this a bug, or
am i missing something?

thanks,
neal
