Not gonna lie, I've lurked on gbatemp for years, but I finally registered to join in on PS4 discussion, especially since I've got the same model and network issues you do Thank you for providing insight on this since documentation on PS4 Pro Linux nuances is found entirely through forum posts and Youtube guides. Keep us updatedOk, so, I got tired of waiting for a new kernel and spent the last 6 days learning how to compile one for baikal PS4 Pro's.
Got USB dongle support working - which is a start.
Need 5 posts to be able to post links. Will post in a few.
Should work for 7215B, 7216B any anything else that uses a Baikal chip.
