4.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jarod Wilson <[email protected]> [ 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.
