Linux kernel source tree
cfd9e7b74a
This adds both the source and destination chain id to the information kept
for enabled port lookups.
This allows enabling and disabling a chain of lookups by walking the chain
information for a port.
This changes the way that VCAP lookups are enabled from userspace: instead
of one matchall rule that enables all the 4 Sparx5 IS2 lookups, you need a
matchall rule per lookup.
In practice that is done by adding one matchall rule in chain 0 to goto IS2
Lookup 0, and then for each lookup you add a rule per lookup (low priority)
that does a goto to the next lookup chain.
Examples:
If you want IS2 Lookup 0 to be enabled you add the same matchall filter as
before:
tc filter add dev eth12 ingress chain 0 prio 1000 handle 1000 matchall \
skip_sw action goto chain 8000000
If you also want to enable lookup 1 to 3 in IS2 and chain them you need
to add the following matchall filters:
tc filter add dev eth12 ingress chain 8000000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8100000
tc filter add dev eth12 ingress chain 8100000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8200000
tc filter add dev eth12 ingress chain 8200000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8300000

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.
