b0e567806d [DCCP] Introduce dccp_timestamp
To start the timestamps with 0.0ms, easing the integer maths in the CCIDs, this
probably will be reworked to use the to be introduced struct timeval_offset
infrastructure out of skb_get_timestamp, etc.

a84ffe4303 [DCCP]: Introduce DCCP_SOCKOPT_PACKET_SIZE
So that applications can set dccp_sock->dccps_pkt_size, that in turn
is used in the CCID3 half connection init routines to set
ccid3hc[tr]x_s and use it in its rate calculations.

1bc0986957 [DCCP]: Fix the timestamp options
This changes timestamp, timestamp echo, and elapsed time to use units of 10
usecs as per DCCP spec. This has been tested to verify that times are correct.
Also fixed up length and used hton/ntoh more.

Still to add in later patches:
- actually use elapsed time to adjust RTT
(commented out as was prior to this patch)
- send options at times more closely following the spec
(content is now correct)

64cf1e5d8b [DCCP]: Finish the TIMEWAIT minisock support
Using most of the infrastructure TCP uses, with a dccp_death_row,
etc. As per my current interpretation of the draft what we have with
this changeset seems to be all we need (or very close to it 8)).

1d3de414eb [NETFILTER]: New iptables DCCP protocol header match
Using this new iptables DCCP protocol header match, it is possible to
create simplistic stateless packet filtering rules for DCCP.  It
permits matching of port numbers, packet type and options.

5a47a470e6 [DCCP]: make <linux/dccp.h> include-able from userspace
The protocol header files in <linux/foo.h> are usually structured in a
way to be included by userspace code.  The top section consists of
general protocol structure definitions, typedefs, enums - followed by
an #ifdef __KERNEL__ section.

Currently <linux/dccp.h> doesn't follow that convention and can
therefore not be used from userspace.  However, for example iptables'
libipt_dccp.c actually needs various definitions from there.

7c657876b6 [DCCP]: Initial implementation
Development to this point was done on a subversion repository at:

http://oops.ghostprotocols.net:81/cgi-bin/viewcvs.cgi/dccp-2.6/

This repository will be kept at this site for the foreseable future,
so that interested parties can see the history of this code,
attributions, etc.

If I ever decide to take this offline I'll provide the full history at
some other suitable place.
