Is it better to put num_dbc in qaic_device_config?
I think there is no clear "right answer". All known devices use 16.
There may be a future device which has a different value, at which point
I think this needs to be in qaic_device_config. For this patch, I was
conservative and only included items in qaic_device_config which do vary
between the known devices.
I'll think in this a bit more.
Thanks,
Lizhi
