Remove the use of splimp() from the NetBSD kernel. splnet()
...
and only splnet() is allowed for the protection of data structures
used by network devices.

attempt to fast-forward it out.

One more tweak to the checksum hack, and I promise I'm done. B-)

Absolutely minor tweak to generate better code.

Update the comment about the checksum hack. It was way out of date.

Modify the checksum slightly so that the htons()s can all be combined.

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.

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.

- 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.

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).
