T2 is working but to make this happen the T2 Author has an own repo for
patches to apply. In the following video he publishes his view on how
well the ps3disk is maintained and tested by the linux kernel community.
My impression of this is that ps3disk is not tested on hardware at all.
You can find this in a youtube video: “I can't believe VIP Linux kernel
developer BROKE PS3 support” but watch out that you are in a good mood
otherwise it is pulling you down like me...

The commit that is breaking the function is:
commit a7f18b74dbe171625afc2751942a92f71a4dd4ba

Thanks, I see no evidence of this ever being reported upstream, which
makes it rather difficult to be aware of the issue...

This fixes are not in Mainline up to today. So who beside T2 Linux is
using this? You can find more of those breaking patches... and videos...

Care to tell us where the fix is?

/me looks at the bad commit...

Oh, dev->bounce_size is used before set. Patch sent.

The following points are also in the list of reasons:
- This driver has a maximum 54MBit/s as it supports only 802.11 b/g.
- Using this hardware is security wise not state of the art as WPA3 is
   not supported.

If you only do VPN over such an insecure link, I guess it's still safe?

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
