As a preparatory patch to introduce support for PRP protocol, add a protocol ops ptr in the private hsr structure to hold function pointers as some of the functions at protocol level packet handling is different for HSR vs PRP. It is expected that PRP will add its of set of functions for protocol handling. Modify existing hsr_announce() function to call proto_ops->send_sv_frame() to send supervision frame for HSR. This is expected to be different for PRP. So introduce a ops function ptr, send_sv_frame() for the same and initialize it to send_hsr_supervsion_frame(). Modify hsr_announce() to call proto_ops->send_sv_frame(). Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
