====================
Fixes for KSZ DSA switch

These patches fix issues I encountered while using a KSZ9897 as a DSA
switch with a broadcom GENET network device as the DSA master device.

PATCH 1 fixes an invalid access to an SKB in case it is scattered.
PATCH 2 fixes incorrect hardware checksum calculation caused by the DSA
tag.

Changes in v2:
- instead of linearizing the SKBs only for KSZ switches ensure linearized
  SKBs for all tail taggers by clearing the feature flags NETIF_F_HW_SG and
  NETIF_F_FRAGLIST (suggested by Vladimir Oltean)

The patches have been tested with a KSZ9897 and apply against net-next.
