Hello Rafael Almeida.
I noticed your patch adding DESTDIR support in the latest iproute2 release.
Much appreciated! Soon the debian packages might be able to move to actually
using "make install" rather then it's own installation procedure when
building packages. I've noticed something that will break though....
Debian packages usually sets DESTDIR=debian/tmp/ and packages the contents
of that directory as if it where the root file system. This will break
the /usr/lib/{tc,ip}/ module loading, because they DESTDIR (/usr) will be
/whatever-the-build-path-was/debian/tmp/lib/{tc,ip}/.
I beleive others usually call this the LIBDIR to make the separation between
DISTDIR being the (possibly temporary) place things are put when build is
done, and LIBDIR (and others) are used for actual runtime paths.
I'm attaching a patch that I think fixes this, but would be really happy if
you could have a look at to verify I'm not screwing something up.

Patch adds generic size table that is similiar to rate table, with
difference that size table stores link layer packet size.

After changing the DESTDIR the installated binaries have some issues
due to hard coded paths. For example, using distributions on NetEm
would segfault.
I've changed iplink.c and tc_util.c so they are now aware of DESTDIR.
Along with that change I needed to change the main Makefile so it
defines the DESTDIR macro when calling gcc.
I also changed the paths so that during the installation sbin, etc,
share and lib directories are created directly inside of the DESTDIR,
instead of creating a usr directory inside that. That's the behaviour
of most packages out there, so I think most users will be expecting
that to happen.

The current iproute version uses "protocol all" by default
if its not specified. This is actually only useful for creating
new filters, on deletion an unset protocol is treated as wildcard.

[IPROUTE]: Fix classifier help
The new check whether the user has specified a protocol makes
"ip filter <type> help" fails with "protocol is required".
This could be fixed by moving it further down, but a more user-friendly
way it to simply use ETH_P_ALL as default if nothing is specified.

After further investigation it seems clear to me that reverting the
commit 720a2e8d990707749b2... is the correct thing to do, since the real
fix for the problem this commit was supposed to fix was instead fixed in
commit c29391c7c68f031e246c...
Whatever you specify after a u32 police you will now get a syntax error,
and according to "tc filter add u32 help" there are several things that
you are supposed to be able to specify after a police.
This reverts commit 720a2e8d99.
New iptables 1.4.0 has some library names changed from libipt to libxt.
It is prefferable also to open libxt_ first, as newer "style".

Hello Stephen,
As the current maintainer of iproute2 package, you could be interested
in including the attached patch that allow using masks in the fw filter
of the tc utility (very useful at least for me). AFAK, it works at least
from iproute2 version 2.6.20-?. Feel free to make the appropriate
cleaning changes if necessary, or contact me if you see any trouble.
Best regards,
François Delawarde.

Follow up patch to "Fix overflow in time2tick / tick2time." which switches
the remaining two helper functions from long to unsigned as well.
These functions are only used in "tc/q_hfsc.c" where both the passed argument
and the place the return value is stored are unsigned/u32 variables, so this
change should be safe to make but hasn't been tested as extensively as the
time2tick patch.
