The qcom_emac driver in the installer is able to get a DHCP lease once I
blacklisted the mlx5_core module.

Title:
[Zesty] d-i: replace msm_emac with qcom_emac
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
We landed a patch to support msm_emac module in initrd for amberwing
platforms. But the upstream driver has since been renamed to qcom_emac. This
module is needed in d-i's initrd so that these nics can be used to d-i install
the system. The driver already exists in the zesty kernel under
drivers/net/ethernet/qualcomm/emac/
Revert commit 14893d91c9c391f8a4c2668b96ffe60aa728ad23 and add
qcom_emac to initrd, and change the module name to qcom_emac.
[Test Case]
D-I install zesty on amberwing platform and notice that DI does not recognize
the onboard two port nic.
[Regression Potential]
At present this driver applies only to amberwing systems, any regression will
be isolated to amberwing platforms. The over all risk of regression is low.
