If we have both phonesim and cdmaphonesim plugins active, we need to

I am a bit lost about the Type attribute. cdmaphonesim is currently
defined as a separate plugin and by the time cdmaphonesim's
parse_config() is invoked, it already knows that it is cdma. Thus, I
don't see why needing another flag indicating this. When you say ignore
the rest, could you pls be more specific about what to ignore and what's
the intention of doing that? Sorry, still learning... :-)
So correct me if I'm wrong, but there's a race between cdmaphonesim and
phonesim plugins:
if phonesim starts first it reads phonesim.conf and creates both
phonesim and cdmaphonesim modems. When cdmaphonesim starts, it tries to
create the modems again, but fails. Similar situation vice-versa.
This is why I'm suggesting the Type attribute. Maybe I'm blind and this
race does not happen?
Now, I understand your point. I checked the log, in my setup,
cdmaphonsim will run first and it will create cdmaphonsim plugin. Next,
phonesim will run and try to create cdmaphonsim plugin with wrong type:
"phonesim" but failed. I.e., we are lucky to have cdmaphonsim run first.
So, the way to fix this is to add a Type=cdma flag under [cdmaphonsim]
and let cdmaphonsim.c only create modem if type is set to cdma. In
addition to this, we also need to modify phonesim.c to ignore any modem
group that has type set to cdma.
Could you pls clarify whether above solution will work?
