57030e2f12 cache IPsec policy on in6?pcb. most of the lookup operations can be bypassed,

cad488d032 sync gif interface code with latest kame. 
IFF_RUNNING is clearified.  attach/detach logic is more clearner.
the old code mistakenly set IFF_UP by itself, now the behavior is gone.

57d1913ebc do not forward packet back to point-to-point interface, if the packet 
matches the ipv6 prefix assigned to the p2p interface (= redirect case).
this leads to pingpong, chews bandwidth.  bad thing is that bad guy from
remote can chew bandwidth.  (follows upcoming internet draft)

ad9d3794b0 Implement support for IP/TCP/UDP checksum offloading provided by 
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
