I see that differently. For me, providing device support for a device A and using similar code for a bunch of devices B to D is a different patch.
I don't think a Signed-off-by is correct here, as Julien is _not_ an author of your patch, as he intended to provide support for the EAP245 and not for the 1-port EAP2x5 devices.

That's nice but irrelevant without proper explanation ("why is EAP245 relevant at all").
If you really want to refer to that prior work, IMO a proper solution would be to just add something like "Implementation of these devices is based on the prior work of XY supporting device YZ in commit xxxxxxxxx."
Then, everybody can look up what XY has done and will see the proper authorship in the reference.

The initial author needs no Co-developed-by, as he is mentioned in the From field.
From/Co-developed-by is about authorship, Signed-off-by is about legal accountability.
The latter is one reason why you technically actually can only add Juliens Signed-off-by if this patch is combined submission of both of you, where both people have actually checked the final patch for correctness. If that's not the case, it's not Co-developed-by, but Julien would be the author, and you would have to note every single change before your Signed-off-by to make obvious which parts are covered by his SoB and what has been changed since then and thus is covered by your SoB.
(example for the latter may be found here: https://github.com/openwrt/openwrt/commit/ed087cba8a8e41f76f9487caa34eff926ea8a065)
Since this appears to me to be "your" patch, and not a submission by both of you, for me it would be more correct to just have your SoB/From: only.
If the original patch was mine, I'd actually be quite mad at you if you used my Signed-off-by for a different submission.
