The introduction of the explicit switchdev bridge port offloading API
has introduced dependency regressions between switchdev drivers and the
bridge, with some drivers where switchdev support was optional before
being now compiled as a module when the bridge is a module, or worse.
This patch makes the switchdev bridge port offload/unoffload events
visible on the blocking notifier call chain, so that the bridge can
indirectly do something when those events happen, without the driver
explicitly calling a symbol exported by the bridge driver.
Vladimir Oltean (2):
net: make switchdev_bridge_port_{,unoffload} loosely coupled with the
bridge
Revert "net: build all switchdev drivers as modules when the bridge is
a module"
