With a current (5.1) kernel version, IPv6 exception routes can't be listed
(ip -6 route list cache) or flushed (ip -6 route flush cache). Kernel
support for this is being added back. Relevant net-next commits:
564c91f7e563 fib_frontend, ip6_fib: Select routes or exceptions dump from RTM_F_CLONED
ef11209d4219 Revert "net/ipv6: Bail early if user only wants cloned entries"
3401bfb1638e ipv6/route: Don't match on fc_nh_id if not set in ip6_route_del()
bf9a8a061ddc ipv6/route: Change return code of rt6_dump_route() for partial node dumps
1e47b4837f3b ipv6: Dump route exceptions if requested
40cb35d5dc04 ip6_fib: Don't discard nodes with valid routing information in fib6_locate_1()
However, to allow the kernel to filter routes based on the RTM_F_CLONED
flag, we need to make sure this flag is always passed when we want cached
routes to be dumped, and we can also pass table and output interface
attributes to have the kernel filtering on them, if requested by the user.
Use the existing iproute_dump_filter() as a filter for the dump request in
iproute_flush(). This way, 'ip -6 route flush cache' works again.
v2: Instead of creating a separate 'filter' function dealing with
RTM_F_CACHED only, use the existing iproute_dump_filter() and get
table and oif kernel filtering for free. Suggested by David Ahern.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
