2017-08-08net: dsa: Remove switchdev dependency from DSA switch notifier chainArkadi Sharshevsky1-2/+4
Currently, the switchdev objects are embedded inside the DSA notifier info. This patch removes this dependency. This is done as a preparation stage before adding support for learning FDB through the switchdev notification chain.

2017-08-08net: dsa: Remove prepare phase for FDBArkadi Sharshevsky1-1/+3
The prepare phase for FDB add is unneeded because most of DSA devices can have failures during bus transactions (SPI, I2C, etc.), thus, the prepare phase cannot guarantee success of the commit stage. The support for learning FDB through notification chain, which will be introduced in the following patches, will provide the ability to notify back the bridge about successful offload.
