Alexander Lobakin says: ==================== net: avoid retpoline overhead on VLAN and TEB GRO dev_gro_receive() uses indirect calls for IP GRO functions, but it works only for the outermost headers and untagged frames. Simple VLAN tag before an IP header restores the performance hit. This simple series straightens the GRO calls for IP headers going after VLAN tag or inner Ethernet header (GENEVE, NvGRE, VxLAN) for retpolined kernels. ====================
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.
