Subject: [PATCH] dsa: mv88e6xxx: Enable forwarding for unknown to the CPU port
Date: Tue, 29 Sep 2015 01:50:56 +0200	[thread overview]
Message-ID: <1443484256-28873-1-git-send-email-andrew@lunn.ch> (raw)

Frames destined to an unknown address must be forwarded to the CPU
port. Otherwise incoming ARP, dhcp leases, etc, do not work.
