- removed dead functions in header files
- deprecated rtnl_class_foreach_*() functions due to their missing
handling possibility of OOM situations
- improved API documentation
Finally got rid of all the qdisc/class/cls code duplication in
the tc module API. The API takes care of allocation/freeing the
tc object specific data.
I hope I got it right this time.
- 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)
So far all common tc atttributes were accessed via specific functions, i.e.
rtnl_class_set_parent(), rtnl_qdisc_set_parent(), rtnl_cls_set_parent()
which implied a lot of code duplication. Since all tc objects are derived
from struct rtnl_tc and these common attributes are already stored in there
this patch removes all type specific functions and makes rtnl_tc_* attribute
functions public.
rtnl_qdisc_set_parent(qdisc, 10);
becomes:
rtnl_tc_set_parent((struct rtnl_tc *) qdisc, 10);
This patch also adds the following new attributes to tc objects therefore
removing them as tc specific attributes:
- mtu
- mpu
- overhead
This allows for the rate table calculations to be unified as well taking into
account the new kernel behavior to take care of overhead automatically.
