From: Davide Caratti <dcaratti@redhat.com> [ Upstream commit 1afa3cc90f8fb745c777884d79eaa1001d6927a6 ] 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.
