* [CCID3]: Interface CCID3 code with newer Loss Intervals DatabaseGerrit Renker2008-01-28
| | | | | | | | | | | | | | | | This hooks up the TFRC Loss Interval database with CCID 3 packet reception. In addition, it makes the CCID-specific computation of the first loss interval (which requires access to all the guts of CCID3) local to ccid3.c. The patch also fixes an omission in the DCCP code, that of a default / fallback RTT value (defined in section 3.4 of RFC 4340 as 0.2 sec); while at it, the upper bound of 4 seconds for an RTT sample has been reduced to match the initial TCP RTO value of 3 seconds from[RFC 1122, 4.2.3.1].

* [TFRC]: Put RX/TX initialisation into tfrc.cGerrit Renker2008-01-28
| | | | | | | | | | This separates RX/TX initialisation and puts all packet history / loss intervals initialisation into tfrc.c. The organisation is uniform: slab declaration -> {rx,tx}_init() -> {rx,tx}_exit() Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

* [TFRC]: Provide central source file and debug facilityGerrit Renker2008-01-28
This patch changes the tfrc_lib module in the following manner: (1) a dedicated tfrc source file to call the packet history & loss interval init/exit functions. (2) a dedicated tfrc_pr_debug macro with toggle switch `tfrc_debug'. Commiter note: renamed tfrc_module.c to tfrc.c, and made CONFIG_IP_DCCP_CCID3 select IP_DCCP_TFRC_LIB.
