From 8b1efc0f83f1f75b8f85c70d2211007de8fd7633 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Thu, 20 Oct 2016 23:25:27 -0400 Subject: net: remove MTU limits on a few ether_setup callers These few drivers call ether_setup(), but have no ndo_change_mtu, and thus were overlooked for changes to MTU range checking behavior. They previously had no range checks, so for feature-parity, set their min_mtu to 0 and max_mtu to ETH_MAX_MTU (65535), instead of the 68 and 1500 inherited from the ether_setup() changes. Fine-tuning can come after we get back to full feature-parity here.
