mainlining shenanigans

Add TC-MATCHALL classifier offload with TC-POLICE action applied for all outgoing traffic on the underlying interface. Split flow block offload to support both egress and ingress classification. For example, to rate limit all outgoing traffic to 1 Gbps: $ tc qdisc add dev enp2s0f4 clsact $ tc filter add dev enp2s0f4 egress matchall skip_sw \ action police rate 1Gbit burst 8Kbit Note that skip_sw is important. Otherwise, both stack and hardware will end up doing policing. Policing can't be shared across flow blocks. Only 1 egress matchall rule can be active at a time on the underlying interface. v5: - No change. v4: - Removed check to reject police offload if prio is not 1. - Moved TC_SETUP_BLOCK code to separate function. v3: - Added check to reject police offload if prio is not 1. - Assign block_shared variable only for TC_SETUP_BLOCK. v2: - Added check to reject flow block sharing for policers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
