Alexander Lobakin says: ==================== skbuff: micro-optimize flow dissection This little number makes all of the flow dissection functions take raw input data pointer as const (1-5) and shuffles the branches in __skb_header_pointer() according to their hit probability. The result is +20 Mbps per flow/core with one Flow Dissector pass per packet. This affects RPS (with software hashing), drivers that use eth_get_headlen() on their Rx path and so on. From v2 [1]: - reword some commit messages as a potential fix for NIPA; - no functional changes. From v1 [0]: - rebase on top of the latest net-next. This was super-weird, but I double-checked that the series applies with no conflicts, and then on Patchwork it didn't; - no other changes.

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.
