net/sched: pkt_cls: change tc actions order to be as the user sets

2016-09-28T09:02:44+00:00

Currently the created tc actions list is reversed against the order
set by the user.
Change the actions list order to be the same as was set by the user.

This patch doesn't affect dump actions behavior.
For dumping, action->order parameter is used so the list order doesn't
matter.

net: cls_bpf: limit hardware offload by software-only flag

2016-09-21T23:50:02+00:00

Add cls_bpf support for the TCA_CLS_FLAGS_SKIP_HW flag.
Unlike U32 and flower cls_bpf already has some netlink
flags defined.  Create a new attribute to be able to use
the same flag values as the above.

Unlike U32 and flower reject unknown flags.

net: cls_bpf: add hardware offload

similar to what have been done with U32 and flower.

net_sched: properly handle failure case of tcf_exts_init()

2016-08-23T00:02:31+00:00

After commit 22dc13c837c3 ("net_sched: convert tcf_exts from list to pointer array")
we do dynamic allocation in tcf_exts_init(), therefore we need
to handle the ENOMEM case properly.

net_sched: convert tcf_exts from list to pointer array

2016-08-17T23:27:51+00:00

As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.

The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

net/sched: Add match-all classifier hw offloading.

2016-07-25T06:11:59+00:00

Following the work that have been done on offloading classifiers like u32
and flower, now the match-all classifier hw offloading is possible. if
the interface supports tc offloading.

To control the offloading, two tc flags have been introduced: skip_sw and
skip_hw. Typical usage:

tc filter add dev eth25 parent ffff: 	\
	matchall skip_sw		\
	action mirred egress mirror	\
	dev eth27

net: sched: fix tc_should_offload for specific clsact classes

2016-06-07T23:59:53+00:00

When offloading classifiers such as u32 or flower to hardware, and the
qdisc is clsact (TC_H_CLSACT), then we need to differentiate its classes,
since not all of them handle ingress, therefore we must leave those in
software path. Add a .tcf_cl_offload() callback, so we can generically
handle them, tested on ixgbe.

net/sched: cls_flower: Hardware offloaded filters statistics support

2016-05-16T17:43:50+00:00

Introduce a new command in ndo_setup_tc() for hardware offloaded
filters, to call the NIC driver, and make it update the statistics.
This will be done before dumping the filter and its statistics.
