This patch adds support for tc flower hardware offload on the ingress path. Shared filter blocks are supported by sharing a single ACL table between multiple ports. The following flow keys are supported: - Ethernet: dst_mac/src_mac - IPv4: dst_ip/src_ip/ip_proto/tos - VLAN: vlan_id/vlan_prio/vlan_tpid/vlan_dei - L4: dst_port/src_port As per flow actions, the following are supported: - drop - mirred egress redirect - trap Each ACL entry (filter) can be setup with only one of the listed actions. A sorted single linked list is used to keep the ACL entries by their order of priority. When adding a new filter, this enables us to quickly ascertain if the new entry has the highest priority of the entire block or if we should make some space in the ACL table by increasing the priority of the filters already in the table.

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.
