RE: potential kernel bug issue.
The driver for enic that we ship is 2.3.0-45, as a test, from Cisco.com
the 3.2.210.18-738.12 driver was downloaded and compiled. it functions,
but also reports 20gb link and with nothing above 10gb advertisements.

RE: it being a kernel bug
A link can span multiple interfaces, so the reported speed of a link can
be higher than the individual interfaces . See page 5

This appears to be a bug in the cisco enic driver. It will always
report 1baseT/Full, regardless of the link speed itself. It has
always been like this in mainline, and I am also not supprised if the
upstream driver is also similarly broken.

It may be that we are not able to assume these figures are the same.

Ahh yes, comment #11 even details how this is reasonable, that the
interface speed exceeds the per-link advertisments.

Testing with MAAS 2.6 and the network interfaces were detected
correctly. This points to MAAS 2.7 having a bug in the way it tests the
link speeds. Also, the smartctl-validate tests were successful

Thanks for the background info, in 2.7 MAAS started modelling the speeds
of interfaces and links, so I expect that 2.6 will not have the same
problem.

Title:
Kernel does not report interface speed correctly for Cisco UCS B
MAAS 2.7 introduced network testing. As part of network testing we added
the following features which require accurate interface and link speed
information.
1. The interface and uplink speeds are now shown in the API and over the UI.
2. MAAS now warns when an interface is connected to an uplink wh
That is not an easy answer.
In the world of UCS, there are several factors that can affect this:
1) Type of IOM (I/O Module)
2) Port config of the IOM (single link or port-channel)
3) Number of inks from the Fabric Interconnect to said IOM
4) Model of adapter in the blade.
