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
