3406f0a3dd The "gif*" tunnelling interface does everything ipip does. 
Move usage example from ipip.4 to gif.4
Excise ipip and stitch up the scars.

10444ca48f In in_savemkludge() and in_restoremkludge(), don't insert into a new

75c5a16cfc Enforce a lower bound of 32 for tcp_mssdflt. 
This avoids kernel crashes when we don't handle nonsensial values
like 0 gracefully. Better check here once beforehand than having to
check for non meaningful values in time critical paths (like tcp_output).

Fixes PR 15709.

a7d662b71c Clear M_BCAST and M_MCAST on outgoing mbufs. 
Don't copy ttl from the inner packet to the encapsulating packet. Make
the outer ttl sysctl'able. This should close PR 14269 from Jasper Wallace
(change partly from there) and it makes traceroute work over gre tunnels.

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.

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.
