As far as I can tell, that will not work, because I want to have
multiple station devices per radio, and have each of them be able to
use a different configuration. So, one station may be /g, and
another /n and another /AC. Same with APs. In addition, some
stations may want to use all available rates for their mode, and
others may want to use a fixed rate or subset of available rates.
So let's agree that we're splitting the *used* rates (which we have
today) and the *advertised* rates/modes/...
Yes, I think that will work well, and unless I mis-understand, that
is basically what I implemented so far.
Even if we can't modify the wiphy capabilities, perhaps we could still
handle it more consistently at mac80211 level, e.g. by introducing and
using "sdata->capa.bands" (and similar for all the other wiphy
capabilities you want to manipulate), and then allowing that to point
to something modified?
Copied state might be tricky. I think if we hold any copies of capabilities data in
the sdata, then it should be logically compared with a mask and then treated as an AND with whatever the wiphy
has. I'm reluctant to propose any serious mac80211 change at this point, though perhaps
as more of this type of features are added, then it will become more obvious how
to nicely consolidate things in mac80211.
To be honest, I thought my -v2 patches were fairly non-invasive compared to my
normal hackings :)
Thanks,
Ben
