5571e920d6 senderr needs only be declared when PFIL_HOOKS is defined 2001-06-12 17:55:52 +00:00

bdbfdf946d run pfil_hooks for IPv6 forwarding path (note: ip6_forward() does not 
call ip6_output()).

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.

c973d6a0eb Skip the pseudo-header if nxt == 0. This is already documented 
in in6_cksum(9) and is also the behavior of the i386 optimized
