[PATCH 4.10 34/63] team: use ETH_MAX_MTU as max mtu

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jarod Wilson <redacted>


[ 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.
