[PATCH 1/3] Bluetooth: Add new quirk for broken local ext features max_page

[Marcel Holtmann]

Hi Vasily,

>> maybe just the read sync train params command is broken? Can you change the init code and not send it and see if the rest of the init phase proceeds. I would rather have the secure connections actually tested before dismissing it altogether.

check if removing the read sync trains params command makes the controller initialize and usable. Then we see about the rest.
