Add the vlan id and protocol to the flow tuple to uniquely identify flows from the receive path. For the transmit path, dev_hard_header() on the vlan device push the headers. This patch includes support for two vlan headers (QinQ) from the ingress path. Add a generic encap field to the flowtable entry which stores the protocol and the tag id. This allows to reuse these fields in the PPPoE support coming in a later patch. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
