- designate your patch to a tree - ``[PATCH net]`` or ``[PATCH net-next]``
- for fixes the ``Fixes:`` tag is required, regardless of the tree
- don't post large series (> 15 patches), break them up
- don't repost your patches within one 24h period
- reverse xmas tree

version that should be applied. If there is any doubt, the maintainer

How do I divide my work into patches?
-------------------------------------
Put yourself in the shoes of the reviewer. Each patch is read separately
and therefore should constitute a comprehensible step towards your stated
goal.
Avoid sending series longer than 15 patches. Larger series takes longer
to review as reviewers will defer looking at it until they find a large
chunk of time. A small series can be reviewed in a short time, so Maintainers
just do it. As a result, a sequence of smaller series gets merged quicker and
with better review coverage. Re-posting large series also increases the mailing
list traffic.
I made changes to only a few patches in a patch series should I resend only those changed?

What is "reverse xmas tree"?
----------------------------
Netdev has a convention for ordering local variables in functions.
Order the variable declaration lines longest to shortest, e.g.::
struct scatterlist *sg;
struct sk_buff *skb;
int err, i;
If there are dependencies between the variables preventing the ordering
move the initialization out of line.
I am working in existing code which uses non-standard formatting. Which formatting should I use?

Select this option if you want to use hardware accelerated
implementations of CRC algorithms. With this option, you
can optimize the computation of CRC-32 (IEEE 802.3 Ethernet)
and CRC-32C (Castagnoli).
It is available with IBM z13 or later.
