Each nexthop group contains an indication if it has IPv4 nexthops
('has_v4'). Its purpose is to prevent IPv6 routes from using groups with
IPv4 nexthops.
However, the indication is not updated when a nexthop is removed. This
results in the kernel wrongly rejecting IPv6 routes from pointing to
groups that only contain IPv6 nexthops. Example:
# ip nexthop replace id 1 via 192.0.2.2 dev dummy10
# ip nexthop replace id 2 via 2001:db8:1::2 dev dummy10
# ip nexthop replace id 10 group 1/2
# ip nexthop del id 1
# ip route replace 2001:db8:10::/64 nhid 10
Error: IPv6 routes can not use an IPv4 nexthop.
Solve this by updating the indication according to the new set of
member nexthops.

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.
