Merge branch 'Propagate-extack-for-switchdev-LANs-from-DSA'
Vladimir Oltean says:
====================
Propagate extack for switchdev VLANs from DSA
This series moves the restriction messages printed by the DSA core, and
by some individual device drivers, into the netlink extended ack
structure, to be communicated to user space where possible, or still
printed to the kernel log from the bridge layer.
====================
