Yes, please introduce a feature-bitfield at some location in SHM that's unused
by the proprietary firmware. This bitfields would contain a bit for QoS and
a bit for hwcrypto.
Also change your firmware so the driver detects it as open-source firmware.
I think that's done by writing 0xFFFF to the date/time field in SHM. I don't
quite remember, but it's something like that.
Note that this might mean that the firmware watchdog in the driver will trigger,
as that's enabled by the open-source-firmware-flag. We might want to temporarly
disable the watchdog in the driver for the time being.
