Note: The code for this is not upstream yet.
Extends the link api to allow address family modules to fill a link
message and implements a AF_INET address family link module which
uses the new interface.
This feature isn't upstream yet. It's required to test a patch in
my local tree.
Makes the link parser understand IFLA_AF_SPEC and call the address
family specific parser.
This will fix finding libs while link, by adding them to LDFLAGS
[It's no ideal but it's less of a mess than what we have now. -tgraf]

Adds a family argument which allows to request link dumps for a certain
address family. This allows to f.e. dump ipv6 specific statistics and data.
nl-link-list --family inet6
Introduces a new API to handle address familiy specific link data such as
IFLA_PROTINFO. It provides entry hooks for parsing IFLA_PROTINFO attributes
and allows to include the parsed data when a link object is dumped.
- parse IFLA_IFALIAS if available
- provides API to access/change ifalias
rtnl_link_get_ifalias(link)
rtnl_link_set_ifalias(link, alias)
- extends nl-link-set to test functionality
Manually editing etc/libnl/classid before adding tc objects is a pain.
This patch adds code to attempt auto generating a unique tc id which
will then be assigned to the provided name and added to the classid
file.
This will make the following commands work with prior definitions of
the names "top" and "test"
sudo sbin/nl-qdisc-add --dev eth0 --parent root --id top htb
sudo sbin/nl-class-add --dev eth0 --parent top --id test htb --rate 100mbit
It will generate the following ids automatically:
4001: top
4001:1 test
The only part of commit d378220c (src/nf-queue.c: cleanup and improve
performance of test program for NF_QUEUE) that actually makes sense is
the increase in receive buffer size. Issuing verdicts for IDs not delivered
to userspace is a wasted effort since the kernel drops packets itself when
netlink message delivery fails. This would actually have been noticed
by a return value of -ENOENT if the result of nfnl_queue_msg_send_verdict()
would have been checked.

- Fixes a bunch of bugs related to ematches
- Adds support for the nbyte ematch
- Adds a bison/flex parser for ematch expressions, expressions
may look like this:
ip.length > 256 && pattern(ip6.src = 3ffe::/16)
documenation on syntax follows
- adds ematch support to the basic classifier (--ematch EXPR)
