Linux kernel source tree
fe60065689
Prepare the HMAC key when it is added to the kernel, instead of preparing it implicitly for every packet. This significantly improves the performance of seg6_hmac_compute(). A microbenchmark on x86_64 shows seg6_hmac_compute() (with HMAC-SHA256) dropping from ~1978 cycles to ~1419 cycles, a 28% improvement. The size of 'struct seg6_hmac_info' increases by 128 bytes, but that should be fine, since there should not be a massive number of keys.

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 reStructuredText 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.
