Looks mostly good now, a few small details still.

The added pldm-interface is hard to review in depth since documentation is missing mostly and there are no (unit-)tests.

We can merge it assuming that its good for now, but an issue regarding documentation and tests would be good.

Looks good to me now 👍🏼

Just one small thing:
The CI wasn't configured for a cargo workspace environment, thus the tests only run on the root package.
Adding the --workspace option to the the cargo test invocation should be sufficient to also cover unit tests from the pldm-common and pldm-interface. All other checks should be ok as they are for now.
I noticed that one doc-test is failing when testing this, but the change is small, the import just needs to be changed from pldm_lib to pldm_common there.

One doc test is failing in pldm-common/src/protocol/firmware_update.rs:356 f..

The import needs to be changed from pldm_lib to pldm_common.
