Thanks, You-Sheng and Hui, I would suggest (and maybe that is what you meant)
to use dkms (remove or uninstall for the 5.4 kernel version) to drop the built
dkms module from the 5.4 kernel as a first test. That way it is available for
any older kernel as long as they are kept.
If this works and it is unlikely to have to go back to 5.3, then it is better
to completely remove the backport driver. Otherwise it gets rebuild/installed
for every kernel update.
I would also take back (at least for now) the wont-fix status for the
dkms package. With the 5.4 kernel being the latest HWE kernel for
Bionic, we should see whether we can make it not compiling for 5.4.

When booting into linux-image-5.4.0-42-generic networking grinds to a
halt. It is 10000x times slower than usual.
Selecting an older kernel like linux-image-5.3.0-62-generic makes
networking normal again.
