selftests: netdevsim: Add fib_notifications test
Add test to check fib notifications behavior. The test checks route addition, route deletion and route replacement for both IPv4 and IPv6. When fib_notify_on_flag_change=0, expect single notification for route addition/deletion/replacement. When fib_notify_on_flag_change=1, expect: - two notification for route addition/replacement, first without RTM_F_TRAP and second with RTM_F_TRAP. - single notification for route deletion. $ ./fib_notifications.sh TEST: IPv4 route addition [ OK ] TEST: IPv4 route deletion [ OK ] TEST: IPv4 route replacement [ OK ] TEST: IPv6 route addition [ OK ] TEST: IPv6 route deletion [ OK ] TEST: IPv6 route replacement [ OK ] Signed-off-by: Amit Cohen <amcohen@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
