[Bug 1533721] Re: Ethtool didn't support link speed 25Gb 56Gb 100Gb 200Gb

[Rafael David Tinoco]

After talking to Talat:

- What Ubuntu version are you referring to ?
[TB]Ubuntu 14.4.4 trusty 

- Have you tested in newer versions ?
[TB] not tested yet, will test it on Xenial and update.

- What are the steps to reproduce the problem ?
[TB] ethtool <interface>
	See that under "Advertised link modes" not mentioned all the speeds that supported on this network interface 
	ConnectX4 device support several speeds line 10 25 40 50 100 
	With trusty version we see just 
	        Supported link modes:   10000baseKR/Full
                               40000baseCR4/Full
                               40000baseSR4/Full
                               40000baseLR4/Full

- Is there a known fix you are aware of ? Where ?
[TB] yes there are a fix for 56 will search for the commit and send later.

- Is Mellanox responsible for the code being fixed ? Or for the commit(s) fixing the issue ?
[TB] Yes it's fixed, will ask the maintainer of this and update 

I'm coming back to this after some other IB bugs. So, Talat, if you
could provide the commits fixing the issue I would appreciate.

Thank you

Rafael
