+Subject: openvswitch: Set internal device max mtu to ETH_MAX_MTU.
+
+Commit 91572088e3fd ("net: use core MTU range checking in core net
+infra") changed the openvswitch internal device to use the core net
+infra for controlling the MTU range, but failed to actually set the
+max_mtu as described in the commit message, which now defaults to
+ETH_DATA_LEN.
+
+This patch fixes this by setting max_mtu to ETH_MAX_MTU after
+ether_setup() call.
