In-Reply-To: <20171012171823.1431-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@mellanox.com>

Introduce infrastructure that allows drivers to register callbacks that
are called whenever tc would offload inserted rule for a specific block.

In-Reply-To: <20171012171823.1431-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@mellanox.com>

Use previously introduced extended variants of block get and put
functions. This allows to specify a binder types specific to clsact
ingress/egress which is useful for drivers to distinguish who actually
got the block.

In-Reply-To: <20171012171823.1431-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@mellanox.com>

All drivers are converted to use block callbacks for TC_SETUP_CLS*.
So it is now safe to remove the calls to ndo_setup_tc from cls_*
