This patch series brings no functional changes.
It removes the unused switchdev_trans arguments from the dsa_switch_ops
for both MDB and VLAN operations, and provides functions to prepare and
add these objects for a given bitmap of ports.
Vivien Didelot (4):
net: dsa: remove trans argument from vlan ops
net: dsa: remove trans argument from mdb ops
net: dsa: add switch vlan bitmap functions
net: dsa: add switch mdb bitmap functions

The DSA switch VLAN ops pass the switchdev_trans structure down to the
drivers, but no one is using them and they aren't supposed to anyway.
Remove the trans argument from VLAN prepare and add operations.
At the same time, fix the following checkpatch warning:

This patch brings no functional changes.
It moves out the MDB code iterating on a multicast group into new
dsa_switch_mdb_{prepare,add}_bitmap() functions.
This gives us a better isolation of the two switchdev phases.
