1cc58965b6 don't panic when there's no interface address exist for the specified multicast 
outgoing interface (ia == NULL after IFP_TO_IA).

historic behavior (up to revision 1.43) was to use 0.0.0.0 as source address,
but it seems like a mistake according to RFC1112/1122.

28922b9973 use radix table for inbound tunnel lookup (would increase performance 
for machines with a lot of tunnels).
update route cache for IPvX-over-IPv6 tunnel on path MTU discovery.

77c99e8c60 Add in support for timing out IPv4 routes added due to redirects, 
as discussed in tech-net several weeks ago.  It turned out that
KAME had already added this functionality to the IPv6 stack, so
I followed their example in adding the sysctl variables
net.inet.icmp.rediraccept and net.inet.icmp.redirtimeout.

d679590033 Split the pre-computed ifnet checksum flags into Tx and Rx directions. 
Add capabilities bits that indicate an interface can only perform
in-bound TCPv4 or UDPv4 checksums.  There is at least one Gig-E chip
for which this is true (Level One LXT-1001), and this is also the
case for the Intel i82559 10/100 Ethernet chips.

6d0e813f6c Use callouts for TCP timers, rather than traversing the list of 
all open TCP connections in tcp_slowtimo() (which is called 2x
per second).  It's fairly rare for TCP timers to actually fire,
so saving this list traversal is good, especially if you want
to scale to thousands of open connections.

45e02f5ee8 Split tcp_timers() into multiple functions, one for each timer, 
and call it directly from tcp_slowtimo() (via a table) rather
than going through tcp_userreq().

This will allow us to call TCP timers directly from callouts,
in a future revision.

7446fd2bc8 Change the way receive idle time and round trip time are measured. 
Instead of incrementing t_idle and t_rtt in tcp_slowtimo(), we now
take a timstamp (via tcp_now) and use subtraction to compute the
delta when we actually need it (using unsigned arithmetic so that
tcp_now wrapping is handled correctly).

Based on similar changes in FreeBSD.
