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.
u_int8_t array to struct ieee80211_nwid to prepend length field.
The length field is necessary because IEEE 802.11 spec doesn't prohibit
even '\0' for SSID.
Though the name and the value of SIOC... macro is unchanged, this change
breaks binary compatibility. The only affected userland program on the
tree is ifconfig(8).
As Jason suggested on tech-net, it is better than live with problems
since there are no releases for this ioctls yet.
a meaningful option.
- Don't captialize the word address or interface when it refers an arugment.
- Use .Ar macro for dest_address since it is not a keyword.
that gifconfig(8) would issue to configure tunnel endpoints. This
allows IP tunnel interfaces (`gif' right now, and `gre' later) to
be configured with ifconfig(8), and via /etc/ifconfig.<interface>.
Partially taken from similar changes in OpenBSD.
- Const poison the command functions a bit. We really need to clean
up the command function interface.
in_status() handles the whole inet address family. in_alias() handles
printout for single address (for both the primary address or an alias).
it is more consistent with, for example, the way at_status() is used.
rather a bug in the code (which is violating the C standard by casting
an unaligned pointer to a pointer with more strict alignment constraints).
Fix the code to not do such things. Fixes port-alpha/9494.
