Use existing compile flag to indicate that input() is not used
by tc ematch, fixes compiler warning.

yyerror() should take const char * on current bison.

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.

get_distribution() returns an int.

This patch emulates 'netstat -ul' behavior, showing 'closed'

Although dirty, this seems like the least invasive way to fix
it and shouldn't really break anything.

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)
tc-hfsc(8): explains command line options briefly
tc(8): adds references to new man pages
Makefile: adds man7 directory to install target
q_hfsc.c: minimal help text changes, consistency with tc-hfsc(8)

Building iproute2 in parallel might hit the race failure:
	emp_ematch.l:2:30: fatal error: emp_ematch.yacc.h:
		No such file or directory
	make[1]: *** [emp_ematch.lex.o] Error 1

This is because we currently allow the yacc/lex files to generate and
compile in parallel.  So add a simple dependency to make sure yacc has
finished before we attempt to compile the lex output.

Alternative fix to problem reported by: Bin Li
The issue is came from https://bugzilla.novell.com/show_bug.cgi?id=681952.

In any previous version (since suse ... 10.0?), ip addr add always returned
the error code 2 in case the ip address is already set on the interface:

    inet 172.16.2.3/24 brd 172.16.2.255 scope global bond0
RTNETLINK answers: File exists
2

On 11.4, it returns the exit code 254:

    inet 172.16.1.1/24 brd 172.16.1.255 scope global eth0
RTNETLINK answers: File exists
254

This of course causes ifup to return an error in this quite common case..
