It's a common need to add new packet templates and to review such changes as well, try to simplify both with the help of a pair macros and aliases. ice_find_dummy_packet() became very complex at this point with tons of nested if-elses. It clearly showed this approach does not scale, so convert its logics to the simple mask-match + static const array. bloat-o-meter is happy about that (built w/ LLVM 13): add/remove: 0/1 grow/shrink: 1/1 up/down: 2/-1058 (-1056) Function old new delta ice_fill_adv_dummy_packet 289 291 +2 ice_adv_add_update_vsi_list 201 - -201 ice_add_adv_rule 2950 2093 -857 Total: Before=414512, After=413456, chg -0.25% add/remove: 53/52 grow/shrink: 0/0 up/down: 4660/-3988 (672) RO Data old new delta ice_dummy_pkt_profiles - 672 +672 Total: Before=37895, After=38567, chg +1.77% Diffstat also looks nice, and adding new packet templates now takes less lines. We'll probably come out with dynamic template crafting in a while, but for now let's improve what we have currently. ==================== 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.
