thorpej	edc01ec330	In addition to the IP flow hash table, put the flows on a list. The table ... is used for fast lookup, the list for traversal of all flows. Also, use PRT timers.	1998-06-02 15:48:03 +00:00

matt	36eac04cc0	Default IP flow to being enabled. Add a sysctl to control the maximum ... number of flows (net.inet.ip.maxflows). If set to 0, will disable fast path forwarding.	1998-05-04 19:24:53 +00:00
thorpej	447384d6b8	- kern/5380 (Dennis Ferguson): fix incremental IP header checksum. ... - kern/5381 (Dennis Ferguson): check IP header checksum in fast forward code. - In ipflow_slowtimo(), if no IP flows are in use, don't bother checking all of the hash buckets.	1998-05-04 05:46:04 +00:00
matt	d4d709f7d0	Add support for "fast" forwarding. Add hooks in if_ethersubr.c and ... if_fddisubr.c to fastpath IP forwarding. If ip_forward successfully forwards a packet, it will create a cache (ipflow) entry. ether_input and fddi_input will first call ipflow_fastforward with the received packet and if the packet passes enough tests, it will be forwarded (the ttl is decremented and the cksum is adjusted incrementally).	1998-04-29 21:37:52 +00:00
