r205066:

Log:
 - restructure flowtable to support ipv6
 - add a name argument to flowtable_alloc for printing with ddb commands
 - extend ddb commands to print destination address or 4-tuples
 - don't parse ports in ulp header if FL_HASH_ALL is not passed
 - add kern_flowtable_insert to enable more generic use of flowtable
   (e.g. system calls for adding entries)
 - don't hash loopback addresses
 - cleanup whitespace
 - keep statistics per-cpu for per-cpu flowtables to avoid cache line contention
 - add sysctls to accumulate stats and report aggregate

r205069:
Log:

r205097:

Log:
 flowtable_get_hashkey is only used by a DDB function - move under #ifdef DDB

 pointed out by jkim@

r205488:

Log:
 - boot-time size the ipv4 flowtable and the maximum number of flows
 - increase flow cleaning frequency and decrease flow caching time
   when near the flow limit
 - stop allocating new flows when within 3% of maxflows don't start
   allocating again until below 12.5%

r201282
-------
The proxy arp entries could not be added into the system over the
IFF_POINTOPOINT link types. The reason was due to the routing
entry returned from the kernel covering the remote end is of an
interface type that does not support ARP. This patch fixes this
problem by providing a hint to the kernel routing code, which
indicates the prefix route instead of the PPP host route should
be returned to the caller. Since a host route to the local end
point is also added into the routing table, and there could be
multiple such instantiations due to multiple PPP links can be
created with the same local end IP address, this patch also fixes
the loopback route installation failure problem observed prior to
this patch. The reference count of loopback route to local end would
be either incremented or decremented. The first instantiation would
create the entry and the last removal would delete the route entry.

r201543
-------
The IFA_RTSELF address flag marks a loopback route has been installed
for the interface address. This marker is necessary to properly support
PPP types of links where multiple links can have the same local end
IP address. The IFA_RTSELF flag bit maps to the RTF_HOST value, which
was combined into the route flag bits during prefix installation in
IPv6. This inclusion causing the prefix route to be unusable. This
patch fixes this bug by excluding the IFA_RTSELF flag during route
installation.

a0021692f2 Merge r196535 from head to stable/8:
Use locks specific to the lltable code, rather than borrow the ifnet
  list/index locks, to protect link layer address tables.  This avoids
  lock order issues during interface teardown, but maintains the bug that
  sysctl copy routines may be called while a non-sleepable lock is held.

c9d763bf41 When an interface address is removed and the last prefix
route is also being deleted, the link-layer address table
(arp or nd6) will flush those L2 llinfo entries that match
the removed prefix.
