defaults.
Default to color numbers in reverse order to CPU numbers (instead of
in the same order with white first and wrapping to dark grey), so that
the brightest bright colors are used first. Don't use dark grey at all;
replace it by dark green.
Syscons has too many compile-time options, but this one is needed in
in case the defaults give something like white on white, or the user
really hates this feature and can't wait to turn it off in rc.

when to use assert, as well as providing a bad example of using
assert. While not strictly necessary, experience has shown issues
with poor assert choice happen often enough that this departure seems
warranted. Also, tighten up the previous example (there's no need
to have extra paragraphs or gratuitously long lines).

The hardware rate limiting feature is enabled by the RATELIMIT kernel
option. Please refer to ifconfig(8) and the txrtlmt option and the
SO_MAX_PACING_RATE set socket option for more information. This
feature is compatible with hardware transmit send offload, TSO.
A set of sysctl(8) knobs under dev.mce.<N>.rate_limit are provided to
setup the ratelimit table and also to fine tune various rate limit
related parameters.

This driver was merged to HEAD one week prior to Exar publicly announcing they
had left the Ethernet market. It is not known to be used and has various code
quality issues spotted by Brooks and Hiren. Retire it in preparation for
FreeBSD 12.0.

Each TCP connection that uses the system default cc_newreno(4) congestion
control algorithm module leaks a "struct newreno" (8 bytes of memory) at
connection initialisation time. The NULL-pointer dereference is only germane
when using the ABE feature, which is disabled by default.
While at it:
- Defer the allocation of memory until it is actually needed given that ABE is
optional and disabled by default.
- Document the ENOMEM errno in getsockopt(2)/setsockopt(2).
- Document ENOMEM and ENOBUFS in tcp(4) as being synonymous given that they are
used interchangeably throughout the code.
- Fix a few other nits also accidentally omitted from the original patch.

This hardware isn't totally ancient, about equal to a mxge(4) or mlx4en(4),
but the company was sold to Exar which then promptly exited the Ethernet
business so the card was commercially available for under 2 years. On deep
search, the only usage of these cards I found was by the importing of the
driver. There are code quality issues identified by Brooks and Hiren and
no visible use nor maintainership that warrant removal from FreeBSD 12.0.

Currently when net.inet.carp.allow=0 CARP state remains as MASTER, which is
not very useful (if there are other masters -- it can lead to split brain,
if there are none -- it makes no sense). Having it as INIT makes it clear
that carp packets are disabled.

This is a component of a system which lets the kernel dump core to
a remote host after a panic, rather than to a local storage device.
The server component is available in the ports tree. netdump is
particularly useful on diskless systems.
The netdump(4) man page contains some details describing the protocol.
Support for configuring netdump will be added to dumpon(8) in a future
commit. To use netdump, the kernel must have been compiled with the
NETDUMP option.
The initial revision of netdump was written by Darrell Anderson and
was integrated into Sandvine's OS, from which this version was derived.
