What you expected to happen: Setting the MTU at 9000 has worked fine until a recent kernel version linux-image-4.8.0-48-generic

What happened instead: Setting jumbo MTU fails:

sudo ip link set enp0s25 mtu 9000
RTNETLINK answers: Invalid argument
sudo ip link set enp0s25 mtu 8000
RTNETLINK answers: Invalid argument
sudo ip link set enp0s25 mtu 4000
RTNETLINK answers: Invalid argument

Anything from 1500 and below works OK.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

The last version to work correctly was linux-image-4.8.0-46-generic.

I observe the same problem with
Ubuntu 16.04.02, Kernel 4.8.0.49 and Network card Intel X520-DA2 (10GbE)

I don't see that problem with Ubuntu 16.04.02 Kernel 4.8.0.36

I can confirm this on kernel 4.8.0-49.52~16.04.1 with - Intel Corporation Ethernet Connection I217-LM (rev 04). This of course wreaked havoc on my openvswitch implementation.
