4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jarod Wilson <jarod@redhat.com>
[ 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.
Fixes: 91572088e3fd ("net: use core MTU range checking in core net infra")
