d93a13cb23 Remove the "The option TCPDEBUG requires option INET." requirement.
In case of !INET we will not have a timestamp on the trace for now
but that might only affect spx debugging as long as INET6 requires
INET.

00db174bc2 To my reading there are no real consumers of ip6_plen (IPv6
Payload Length) as set in tcpip_fillheaders().
ip6_output() will calculate it based of the length from the
mbuf packet header itself.
So initialize the value in tcpip_fillheaders() in correct
(network) byte order.

With the above change, to my reading, all places calling tcp_trace()
pass in the ip6 header via ipgen as serialized in the mbuf and with
ip6_plen in network byte order.
Thus convert the IPv6 payload length to host byte order before printing.

9df79d84c1 Rather than selectively zeroing fields in the tcp_debug structure
throughout tcp_trace(), zero the entire structure up front.

Minor style fixes.

6087c3c29e Add global mutex tcp_debug_mtx, which will protect global TCP debugging
state tcp_debug, tcp_debx.  Acquire and drop as required in tcp_trace().

Move to ANSI C function header, correct prototype types so that short TCP
state is no longer promoted to int unnecessarily.

Add comments.

not working properly with the patch in place.

1094bdca51 This set of changes eliminates the use of MT_TAG "pseudo mbufs", replacing
them mostly with packet tags (one case is handled by using an mbuf flag
since the linkage between "caller" and "callee" is direct and there's no
need to incur the overhead of a packet tag).

This is (mostly) work from: sam

ecd3e8ff5a It's now sufficient to rely on a nested include of _label.h to make sure
all structures in ip_var.h are defined, so remove include of mac.h.

ae8d522734 Sorry in this just befor code freeze commit.
This is fix to usr.sbin/trpt and tcp_debug.[ch]
I think of putting this after 4.0 but,,,

 -There was bug that when INET6 is defined,
  IPv4 socket is not traced by trpt.

 -I received request from a person who distribute a program
  which use tcp_debug interface and print performance statistics,
  that
    -leave comptibility with old program as much as possible
    -use same interface with other OSes

  So, I talked with itojun, and synced API with netbsd IPv6 extension.

makeworld check, kernel build check(includes GENERIC) is done.

But if there happen to any problem, please let me know and
I soon backout this change.

1d5e9e2255 Make INET a proper option.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway.  Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug.  The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

This commit move struct arpcom from <netinet/if_ether.h> to
<net/if_arp.h>.

c5294719c3 Eliminated sloppy common-style declarations. Now there are no duplicated
common labels for LINT.  There are still some common declarations for the
!KERNEL case in tcp_debug.h and spx_debug.h.  trpt depends on the ones in
tcp_debug.h.
