Subject: [PATCH 2/2] netdev: reset peer keys when changing private key
Date: Thu, 24 Jan 2019 17:53:39 -0800 [thread overview]
Message-ID: <20190125015339.27684-2-derrick@pallas.us> (raw)
In-Reply-To: <20190125015339.27684-1-derrick@pallas.us>
Without this change, it can take until the handshake timeout period to
reestablish with the peer. After this change, the handshake occurs as soon
as possible and the link is reestablished much more quickly.
