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.
