Hi Luiz,
quoted hunk ↗ jump to hunk
Both max_num_keys and num_key are 2 octects:

BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 4, Part E
page 1985:

 Max_Num_Keys:
 Size: 2 octets
 Range: 0x0000 to 0xFFFF

 Num_Keys_Read:
 Size: 2 octets
 Range: 0x0000 to 0xFFFF

I have no idea on how this could be wrong all these years. I added this back in 2015 :(

However, you also need to touch the user of it

       if (!rp->status && sent->read_all == 0x01) {
                hdev->stored_max_keys = rp->max_keys;
                hdev->stored_num_keys = rp->num_keys;
       }

Regards

Marcel
