commit be18cce7e665b09406c4168fd3da32492dd5d8f3 Author: Jarod Wilson <ja...@redhat.com> Date: Mon Mar 6 08:48:58 2017 -0500 team: use ETH_MAX_MTU as max mtu [ Upstream commit 3331aa378e9bcbd0d16de9034b0c20f4050e26b4 ] This restores the ability to set a team device's mtu to anything higher than 1500. Similar to the reported issue with bonding, the team driver calls ether_setup(), which sets an initial max_mtu of 1500, while the underlying hardware can handle something much larger. Just set it to ETH_MAX_MTU to support all possible values, and the limitations of the underlying devices will prevent setting anything too large.
