# nft add table arp x
# nft add chain arp x y { type filter hook input priority 0\; }
# nft add rule arp x y arp saddr ip 192.168.2.1 counter
Testing this:
# ip neigh flush dev eth0
# ping 8.8.8.8
# nft list ruleset
table arp x {
chain y {
type filter hook input priority filter; policy accept;
arp saddr ip 192.168.2.1 counter packets 1 bytes 46
}
}
You can also specify hardware sender address, eg.
# nft add rule arp x y arp saddr ether aa:bb:cc:aa:bb:cc drop counter

Fix use of font typefaces:
- *bold* for terminals
- 'italic' for non-terminals
- plain for meta-characters
Apart from that:
* Variable definitions require an equals sign
* 'auto-merge' option in set spec does not take a parameter
* List header fields in payload expressions instead of unexplained
placeholder
* Introduce non-terminals in some places to avoid repetitions or clarify
syntax
* Fix syntax for ip6 header expresssion example
* Reorganize ct expression synopsis into four parts:
1) direction not allowed
2) direction optional
3) direction mandatory
4) direction and family mandatory
* Add missing 'version' keyword to osf expression
* Clarify verdict statements example topic
* Add synopses for payload and exthdr statements
* Fix typo: differv -> diffserv
* Reorganize reject statement synopsis to point out which code type
is required for which type arg
* Counter statement requires either one of 'packets' or 'bytes' args or
both, none is an invalid variant
* Limit statement accepts a unit in burst, too
* Improve language in limit statement description a bit

nft doesn't have the context to translate "dns" or "http" as being
service names here.

Instead of meta nftproto, which is a typo.

As suggested at NFWS, the implicit nfproto dependencies generated by
icmp/icmpv6 header field matches should be documented along with how to
achieve matching on unusual packets.

Double-spacing in .txt files has no effect on PDF or man page output and
can make it hard to locate phrases when editing, so remove them.

These were found by a combination of tkdiff and side-by-side man pages
Most changes preserve or (occasionally) fix highlighting, casing or plurality.
No major omissions were found.
- data-types.txt: (Nothing special)
- nft.txt:
-- changed "`nft' stands for Netfilter" back to "`nf' stands for Netfilter"
-- removed mysterious plus sign
- payload-expression.txt:
-- XML had MTU as 16-bit so changed back from 32. Is that correct?
- primary-expression.txt: (Nothing special)
- statements.txt: (Nothing special)
This patch does not address any of the following observations:
1. Title has changed from nft to NFT
2. There is no attempt at justification.
3. There is no attempt at hyphenation.
4. Long lines of code now wrap instead of indenting nicely.
See e.g. "tcp option" line under EXTENSION HEADER EXPRESSIONS
5. Tables have a lot of empty lines in them.
6. Occasionally there is severe wrapping,
e.g. under CHAINS see add/create/delete/&c. which wrap at about cc40.

These were found by ispell -p ./ispell_nft *.txt in nftables/doc.
- ispell.nft: Added some new words
- nft.txt: (nothing special)
- payload-expression.txt: lengthbits and offsetbits were run together
before the conversion to .txt, but the conversion lost the underlining
- primary-expression.txt: ispell suggested rtclassid instead of rtlclassid,
which agres with previous usage
- stateful-objects.txt: (nothing special)
- statements.txt: nonbase chains changed back to non-base chains as it used to
be
