Yeah that seems reasonble. You'd need to store the ctx id in the actual
chanctx struct in hwsim I guess (and unconditionally use 0 for the
non-chanctx case)

I'm not sure we should conflate start-using and change-channel,
userspace might have to set up data structures if it really wants to
track multiple channels, so having a separate start-using might be
easier?
