Subject: [PATCH BlueZ 1/5] mesh: Separate functions for net key add and update
Date: Tue, 5 Feb 2019 23:31:11 -0800 [thread overview]
Message-ID: <20190206073115.28232-2-inga.stotland@intel.com> (raw)
In-Reply-To: <20190206073115.28232-1-inga.stotland@intel.com>
This splits mesh_net_key_add() into two separate functions:
mesh_net_key_add() and mesh_net_key_update().
mesh_net_key_update() essentially replaces mesh_net_kr_phase_one()
since switching to Key Refresh phase one can only be triggered
by successful network key update.
