Bug Description

This is a backport request from Netronome for Ubuntu 18.04 LTS

This patch-set improves MTU handling for flower offload on Netronome SmartNICs.
The max MTU is correctly capped and physical port MTU is communicated to the FW
(and indirectly HW). This prevents the driver from incorrectly reporting a larger
MTU than the HW is configured to handle.

The upstream commits, accepted for v4.17, are:
29a5dcae2790 ("nfp: flower: offload phys port MTU change")
167cebeffadd ("nfp: modify app MTU setting callbacks")

There are also a dependencies on:
ccbdc596f4f6 ("nfp: bpf: don't allow changing MTU above BPF offload limit when active")
b57b62139e53 ("nfp: flower: read extra feature support from fw")

Hi,

I apologise that I am a little unsure of the process here.
This is a rather severe bug from a Netronome point of view which has now been fixed upstream.
Is there a procedure available for backports to be included in an updated Bionic kernel?
