Support for listing IPv6 route exceptions is now back on net-next,
relevant 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()

and this iproute2 patch works together with that as it is. Do I need to
re-submit? Thanks.
