Replace NF_HOOK() based invocation of the netfilter hooks with a private copy of nf_hook_slow(). This copy has one difference: it can return the rx handler value expected by the stack, i.e. RX_HANDLER_CONSUMED or RX_HANDLER_PASS. This is needed by the next patch to invoke the ebtables "broute" table via the standard netfilter hooks rather than the custom "br_should_route_hook" indirection that is used now. When the skb is to be "brouted", we must return RX_HANDLER_PASS from the bridge rx input handler, but there is no way to indicate this via NF_HOOK(), unless perhaps by some hack such as exposing bridge_cb in the netfilter core or a percpu flag. text data bss dec filename 3369 56 0 3425 net/bridge/br_input.o.before 3458 40 0 3498 net/bridge/br_input.o.after This allows removal of the "br_should_route_hook" in the next patch.

README
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.
