Currently, replace assumes that the new group that is given is a fully-formed object. But mpath groups really only have one attribute, and that is the constituent next hop configuration. This may not be universally true. From the usability perspective, it is desirable to allow the replace operation to adjust just the constituent next hop configuration and leave the group attributes as such intact. But the object that keeps track of whether an attribute was or was not given is the nh_config object, not the next hop or next-hop group. To allow (selective) attribute updates during NH group replacement, propagate `cfg' to replace_nexthop() and further to replace_nexthop_grp().

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.
