Subject: [PATCH net-next 0/3] net: remove dsa.h from netdevice.h

In order to push switchdev objects down to DSA drivers, I need to include
switchdev.h in dsa.h. But compilation fails because of a circular dependency
issue, since dsa.h is also included in linux/netdevice.h.

dsa.h is included for two purposes: to have the definition of struct
dsa_switch_tree; and to have access to dsa_uses_tagged_protocol(), used by
netdev_uses_dsa().

This patchset forward declares struct dsa_switch_tree; adds a new uses_hw_tag
boolean to struct net_device, which is more explicit than the DSA helper, and
finally get rid of the dsa.h include.

With this patchset, switchdev.h can safely be included in dsa.h.

Vivien Didelot (3):
  net: dsa: add uses_hw_tag
  net: dsa: include dsa.h in dsa_priv.h
  net: remove dsa.h include from linux/netdevice.h
