call_gro_receive() is used to limit GRO recursion, but it works only with callback pointers. There's a combined version of call_gro_receive() + INDIRECT_CALL_2() in <net/inet_common.h>, but it doesn't check for IPv6 modularity. Add a similar new helper to cover both of these. It can and will be used to avoid retpoline overhead when IP header lies behind another offloaded proto. Signed-off-by: Alexander Lobakin <alobakin@pm.me> Signed-off-by: David S.

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.
