Currently, the individual nexthops member in the group and attributes of the group (e.g., its type) are stored in the same struct (i.e., 'struct mlxsw_sp_nexthop_group'). This is fine since the individual nexthops cannot change during the lifetime of the group. With nexthop objects this is no longer the case. An existing nexthop group can be replaced to use a new set of nexthops. Creating a new struct whenever a group is replaced entails replacing the group pointer of all the routes (i.e., 'struct mlxsw_sp_fib_entry') using the group. Avoid this inefficient step by splitting the nexthop group configuration to a different struct (i.e., 'struct mlxsw_sp_nexthop_group_info'). When a nexthop group is replaced a new group info struct is created and the individual rotues do not need to be touched.

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.
