This patch add rate shaping as well as cell support. The link-rate can be
specified via rate options. Three optional arguments control the cell
knobs: packet-overhead, cell-size, cell-overhead. To ratelimit eth0 root
queue to 5kbit/s, with a 20 byte packet overhead, 100 byte cell size and
a 5 byte per cell overhead:

	tc qdisc add dev eth0 root netem rate 5kbit 20 100 5

This is trivial patch for libnetlink.c in iproute2.

In iproute2/include/linux/netlink.h NLM_F_DUMP is defines as:

   #define NLM_F_DUMP	(NLM_F_ROOT|NLM_F_MATCH)

It is not used in libnetlink.c. If used, the code becomes a bit easier
to read.

Spell check the README files and remove out of date release notes.

Use existing compile flag to indicate that input() is not used

Based on earlier implementation by James Chapman. But instead of
dragging in all of libnl, use existing libnetlink infrastructure.

Based on idea in libmnl, add attribute access functions instead
of explicitly exposing casts. Also handle possible alignment issues
of u64.

Both rtnl_talk and rtnl_dump had a callback for handling portions
of netlink message that do not match the correct pid or seq.
But this callback was never used by any part of iproute2 so remove
it.

New functions to handle u8, u16, u32, u64 and string attribute types.
Use common code for all attribute wrappers.

Avoid having to cast buffer being sent.

Incorporate support for new loss models.

Format man page with conventional style (BNF and italics) to make
it match other pages.

Fix loss model options to match what will implemented!

Keep in sync

The man page for ip command had grown too large to be readable.
Break it up into separate pages.

With help from Eric Dumazet.
Man page is derived in parts from README file contained in
Juliusz Chroboczeks original sfb kernel patch.

Add harddrop support (kernel support added a long time ago), and various
cleanups.

min BYTES, max BYTES are now optional and follow Sally Floyd's
recommendations.

By the way, our default 2% probability is a bit low, Sally recommends 10%.
Not a big deal if upcoming adaptative algo is deployed.

Add ip link command parsing for VF spoof checking enable/disable

V2 - Fixed problem with parsing of dump info on kernels that don't
     support the spoof checking option and also wrapped the ifla_vf_info
     structure in #ifdef __KERNEL__ to prevent user space from directly
     accessing the structure
V3 - Improved parsing of vfinfo
V4 - Put Makefile back to proper list of subdirs
V5 - Remove struct ifla_vf_info, it is only used by the kernel
V6 - Make sure spoof check is reported by the driver - rtnl will set
     it to -1 to indicate driver didn't report a value.

make clean needs to remove all the yacc output files for ematch.

Few minor changes and small additions.

This patch adds detailed documentation for HFSC scheduler. It roughly
follows HFSC paper, but tries to not rely too much on math side of things.
Post-paper/Linux specific subjects (timer resolution, ul service curve, etc.)
are also discussed.

I've read it many times over, but it's a lengthy chunk of text - so try
to be understanding in case I made some mistakes.

tc-hfsc(7): explains algorithm in detail (very long)
