+Subject: [PATCH] BCM270X_DT: Add new Ethernet DT parameters
+
+Add "eth_downshift_after" DT parameter to allow the delay before the
+downshift to be specified. The default is 2 auto-negotiation cycles,
+and legal values are 2, 3, 4, 5 and 0 (disabled).
+
+Add "eth_max_speed" DT parameter as a way of prohibiting 1000Mbps
+links. This can be used to avoid the delay until the downshift mechanism
+activates. Legal values are 10, 100 and 1000, where the default is
+unlimited (effectively 1000Mbps).
