Comment 2 for bug 1820557

While the linux-azure package has the necessary modules for running a virtual machine under Hyper-V, especially in Azure, it does not include every possible driver for PCIe. The other drivers should be available by installing the "linux-modules-extra-azure" metapackage. I have not checked on this particular driver.

Was this an item that was in 4.15 but not 4.18?
