Changes since v2:
* introduce Kconfig count and use it instead of _ON/_OFF in
the first few patches and described below
(I'll squash that later if I don't abandon the whole thing)
Changes since v1:
* use struct static_key_false
* get rid of all those generated macros and use the optimiser
-----
This was an experiment I thought of on Sunday ...
As also explained in the log for patch 3, we have a lot of behaviour
differences in mac80211 based on which driver we're working against.
In many cases (say OpenWRT router, or a phone/tablet, ChromeBook, etc.)
we only have a single driver built into the system though. In that
case we could - theoretically - elide all the code that isn't required
by that driver, but that seems too dangerous.
Instead, use static keys to set a default for each of the flags. If
the flag is selected as _OFF in Kconfig, then any code that needs it
to be on will be placed out of line and the jump NOPed out; if then
a driver registers that actually needs the code the jump will be put
back and the first thing in the out-of-line section will be to check
the real hw flags.
This pretty much results in the same thing as removing the code/if,
but with more safety.
I haven't done any measurements whatsoever, but I think it might be
something to test on a little MIPS router box.
As far as the code is concerned, there are two really ugly things:
1) I still use struct static_key - couldn't quite figure it out
with static_key_false. I think I can replace it easily though.
2) There are a lot of boilerplate ifdefs/macros.
I can't see a way to avoid more of (2), although I think that we
can probably remove it for a lot of flags and just not have this
ability for those that aren't used in RX/TX/status paths. That'd
probably reduce the code quite a bit.
If anyone has an easy setup to test it on a low-power platform that
would be great.

In that case we could practically get rid of the code for the paths that this driver/device doesn't need. Doing that, however, would be rather dangerous. As a decent alternative, use static keys to simply get into the required code path for the single built driver. To achieve this associate with each flag an _ON and _OFF Kconfig symbol. Selecting this symbol in a driver will cause the system to take this as the default state (if both are selected, there's no optimisation at all.) If, for example, the Kconfig selection said that a given flag is expected to always be turned off, then the code depending on it would be placed out-of-line and the jump to it NOPed out. If a different driver that actually requires the code contrary to the Kconfig selection is loaded, the jump will be patched in and the first thing in the out-of-line section will be to check the real hardware flag (since multiple drivers can be loaded.)

This can be useful for certain optimization purposes but I'm sure people will come up with other creative usage.

This handles badly, if a new feature flag is added then all such drivers need to be updated. Instead, use the new Kconfig counters to determine (a) the number of times each feature flag was selected ON (b) the number of mac80211 drivers built if (a) > 0 then it was requested on by at least one driver if (a) < (b) then it was not requested by at least one driver This allows determining whether or not optimisations should be made more easily, and importantly, adding new flags no longer requires editing the Kconfig for all drivers since they won't want the new flag - only the driver it's added for does.
