[PATCH net v3 0/2] net: pse-pd: Fix possible issues with a PSE supporting both c33 and PoDL

[Kory Maincent <kory.maincent@bootlin.com>]

Although PSE controllers supporting both c33 and PoDL are not on the
market yet, we want to prevent potential issues from arising in the
future. Two possible issues could occur with a PSE supporting both c33
and PoDL:

- Setting the config for one type of PSE leaves the other type's config
  null. In this case, the PSE core would return EOPNOTSUPP, which is not
  the correct behavior.
- Null dereference of Netlink attributes as only one of the Netlink
  attributes would be specified at a time.

This patch series contains two patches to fix these issues.

Changes in v3:
- Add a cover letter and the net prefix

Changes in v2:
- Add a patch to deal with null config
