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.
