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.
Lino Sanfilippo (2):
net: dsa: ensure linearized SKBs in case of tail taggers
net: dsa: tag_ksz: dont let the hardware process the layer 4 checksum
