Subject: [PATCH v4 0/3] Correctly perform offloads when VNET_HDR is disabled

Changes since v3:
 - The main change here is that instead of mucking around with checksum bits,
   we instead treat macvtap as macvlan+tap each with separate feature sets.
   tap_features identify the features of only the 'tap' part and we only use
   them when forwarding, essentially making the 'tap' part a pseudo-device.
   To properly handle GSO, we always set NETIF_F_SG | NETIF_F_GSO on the
   'tap' part.

 - The rest of the set is mostly the same in that we allow user to change
   tap offload features whether VNET_HDR is set or cleared.  
 - When VNET_HDR is disabled, we ignore user specified tap offloads.  This
   is now a separate patch so that if there are disagreements, it can
   be easily dropped.

Vlad Yasevich (3):
  macvtap: simplify usage of tap_features
  macvtap: Correctly set tap features when IFF_VNET_HDR is disabled.
  macvtap: Ignore tap features when VNET_HDR is off
