Neeed to backport these:

Bug 752993 - 1.0.4: Interface enp3s0 has MTU of 1492 -- should be 1500 (edit) 

Bug 752508 - NetworkManager 1.0.4 minimizes MTU
Comment 3 Vladimir Benes 2015-09-04 16:07:07 EDT
Verified by setting MTU to 666 that should be ignored and set at least to 1280 so ipv6 can work. Setting MTU to 9000 works as well. Verified on all architectures.
