This patch adds support for the new 'netdev' table. So far, this table allows
you to create filter chains from ingress.
The following example shows a very simple base configuration with one table that
contains a basechain that is attached to the 'eth0':
# nft list table netdev filter
table netdev filter {
chain eth0-ingress {
type filter hook ingress device eth0 priority 0; policy accept;
}
}
You can test that this works by adding a simple rule with counters:
# nft add rule netdev filter eth0-ingress counter

The new syntax is:
nft add chain filter input { hook input type filter priority 0\; policy accept\; }
but the previous syntax is still allowed:
nft add chain filter input { hook input type filter priority 0\; }
this assumes default policy to accept.
If the base chain already exists, you can update the policy via:
nft add chain filter input { policy drop\; }

'nft' documentation is originally contained in the XML file 'doc/nft.xml'.
Processing this file with the proper tools we can obtain a PDF document,
'nft.pdf', and a unix man page, 'nft.8'.
To produce the PDF we need the tool 'dblatex' (current release
pypi.python.org/pypi/dblatex/0.3.5).
To produce the man page we use the tool 'docbook2man'; it is part of the
package 'docbook2X' (docbook2x.sourceforge.net). On some linux
distributions the tool can have slightly different names as 'docbook2x-man'
or 'db2x_docbook2man' so we search for all three names and use the first
one found and issue the command:
# ${DB2MAN} --xinclude $<

This patch changes the default behaviour of nft to not translate IP
addresses to hostnames when printing rules if no options are passed.
The options regarding translations after this patch are:
<no -n/-N> show IP addresses numerically (default behaviour)
-n show IP addresses numerically
-nn show Internet services and uid/gid numerically
-nnn show protocols numerically
-N (--reversedns) translate IP addresses to names
The idea is to avoid breaking existing scripts that most likely rely on
'-n' to save the ruleset, so we reduce the impact of this patch and
provide a default behaviour that doesn't generate network traffic when
listing / saving the ruleset.
Joint work with Pablo.

Trivial fix, but someone filed a bug on it, and it should be fixed. ;)

Let's add info about 'monitor' and 'export'.
While at it, fix other minors things, like the no-netlink return code and
indentations of the document.

Since programlistings are used literally, the should not be indented.
