Get rid of all hardcoded assumptions that buckets in lookup tables correspond to four-bit groups, and replace them with appropriate calculations based on a variable group size, now stored in struct field. The group size could now be in principle any divisor of eight. Note, though, that lookup and get functions need an implementation intimately depending on the group size, and the only supported size there, currently, is four bits, which is also the initial and only used size at the moment. While at it, drop 'groups' from struct nft_pipapo: it was never used. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.
