net/sched: matchall: add missing validation of TCA_MATCHALL_FLAGS
unlike other classifiers that can be offloaded (i.e. users can set flags like 'skip_hw' and 'skip_sw'), 'cls_matchall' doesn't validate the size of netlink attribute 'TCA_MATCHALL_FLAGS' provided by user: add a proper entry to mall_policy. Fixes: b87f7936a932 ("net/sched: Add match-all classifier hw offloading.") Signed-off-by: Davide Caratti <dcaratti@redhat.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
