Subject: [PATCH net v2] net: mvpp2: cls: Add missing NETIF_F_NTUPLE flag

Now that the mvpp2 driver supports classification offloading, we must
add the NETIF_F_NTUPLE to the features list.

Since the current code doesn't allow disabling the feature, we don't set
the flag in dev->hw_features.

Fixes: 90b509b39ac9 ("net: mvpp2: cls: Add Classification offload support")

V2: Rebased on latest -net, added Jakub's Ack, gave more details in the
    commit log about not adding the flag in hw_features.
