Currently, when user adds a tc action and the action gets offloaded,
the user expects the HW stats to be counted also. This limits the
amount of supported offloaded filters, as HW counter resources may
be quite limited. Without counter assigned, the HW is capable to
carry much more filters.
To resolve the issue above, the following types of HW stats are
offloaded and supported by the driver:
any - current default, user does not care about the type.
delayed - polled from HW periodically.
disabled - no HW stats needed.
immediate - not supported.
Example:
tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x11 \
action drop
tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x12 \
action drop hw_stats disabled
tc filter add dev sw1p1 ingress proto ip flower skip_sw ip_proto 0x14 \
action drop hw_stats delayed

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.
