--Problem Description---
kernel does not detect interface in Ubuntu, driver missing in kernel
Contact Information = hasri...@in.ibm.com
---Issue observed---
While installing Ubuntu on a machine with Chelsio card, ubuntu-installer fails
to show the interface name - probable cause would be due to missing driver in
Ubuntu kernel.
Machine Type = Tuleta/Power 8 BML
----Additional Info-----
Installer Shell
-------------------
BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in shell (ash)

Step to reproduce: Install Ubuntu 18.04 on a BML with Chelsio card
interface UP.
---Expected---
Kernel to detect the interface.
---Actual---
Installation fails as interface is not detected from the card.
