There are a few steps that need to happen:
1) determine which kernel modules are required for that hardware
2) check if those kernel modules are build and available from the regular
userspace package
3) check if those kernel modules are included in the udeb kernel package for
the installer
4) check that installer correctly detects and loads those missing modules
and/or said udebs are included in the d-i built itself.
If I am reading the provided debug output right, "cxgb4" driver is
required. I see that there is
kernel/drivers/net/ethernet/chelsio/cxgb4/cxgb4.ko
built in the regular kernel build, and shipped in the -extra package.
(there are a few others as well e.g. iw_cxgb4, cxgb4i, cxgb4vf)
However, I do not see net/ethernet/chelsio/* included in the nic-
modules-4.13.0-32-generic-di_4.13.0-32.35_ppc64el.udeb package as used
by the installer.
Therefore I believe the scope of this bug is to make sure that
net/ethernet/chelsio/* is shipped in the nic-modules udeb package.
Then a d-i rebuild will be needed.
Then the bug reporter can re-validate if this issue becomes resolved.

== Comment: #0 - Harish Sriram
--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

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.
