3d4146e21f Add asm versions of blowfish and des transforms for i386. 
This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!

C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart.  Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so.  It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have.  The DES CBC code
doesn't have this problem.

Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.

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.

65fd25ea82 Restructure the PFIL_HOOKS mechanism a bit: 
- All packets are passed to PFIL_HOOKS as they come off the wire, i.e.
  fields in protocol headers in network order, etc.
- Allow for multiple hooks to be registered, using a "key" and a "dlt".
  The "dlt" is a BPF data link type, indicating what type of header is
  present.
- INET and INET6 register with key == AF_INET or AF_INET6, and
  dlt == DLT_RAW.
- PFIL_HOOKS now take an argument for the filter hook, and mbuf **,
  an ifnet *, and a direction (PFIL_IN or PFIL_OUT), thus making them
  less IP (really, IP Filter) centric.

Maintain compatibility with IP Filter by adding wrapper functions for
IP Filter.

ea9b5a9106 Restructure the Path MTU Discovery code somewhat to avoid 
entering rtentry's for hosts we're not actually communicating
with.

Do this by invoking the ctlinput for the protocol, which is
responsible for validating the ICMP message:
	* TCP -- Lookup the connection based on the address/port
	  pairs in the ICMP message.
	* AH/ESP -- Lookup the SA based on the SPI in the ICMP message.

If validation succeeds, ctlinput is responsible for calling
icmp_mtudisc().  icmp_mtudisc() then invokes callbacks registered
by protocols (such as TCP) which want to take some sort of special
action when a path's MTU changes.  For TCP, this is where we now
refresh cached routes and re-enter slow-start.

As a side-effect, this fixes the problem where TCP would not be
notified when a path's MTU changed if AH/ESP were being used.

XXX Note, this is only a fix for the IPv4 case.  For the IPv6
XXX case, we need to wait for the KAME folks.
