Subject: [patch net-next 2/6] mlxsw: spectrum_router: Embed netevent notifier block in router struct
From: Ido Schimmel <idosch@...lanox.com>
We are going to need to respond to netevents notifying us about
multipath hash updates by configuring the device's hash parameters.
Embed the netevent notifier in the router struct so that we could
retrieve it upon notifications and use it to configure the device.
