I have not tried that out yet, but one important side effect we are
using here is to force HT mode, also for No Ack packets which are
usually sent with the lowest (legacy) rate. We are building fixed
links and want to set a fixed HT rate there, and only this rate should
be used whenever possible (and no legacy rates).
As far as I understand, the ht caps overrides will only override
HT configurations, but what I want is to also let the rate matcher
consider HT rates too and to disable legacy rates completely.
As the mcs masks support has been prepared a long time ago in iw and
mac80211, it did not seem to be the worst idea to finally fill this
gap and implement it. :)
Cheers,
Simon
