This patchs adds the CONFIG_AIO option which allows to remove support
for asynchronous I/O operations, that are not necessarly used by
applications, particularly on embedded devices. As this is a

But there are a lot of people who really don't need these features
and really want the option of leaving them out.
I'll say it one last time.
If you have ipv4 enabled, you need ETHTOOL.

I have drivers which don't even _have_ ethtool support, and they seem to
work fine. But leaving aside the debate on that point, your statement
also seemed to be covering the other patches, such as the IGMP one and

I explained why I didn't want to apply the IGMP one too.
Andrew didn't like my objections, but that doesn't mean I
need to defend my position further.
You said that it was part of the core BSD socket API and Like TCP and

While I agree with Andrew's observation, I'd also respectfully submit
that your argument is more fundamentally bogus than that. TCP and UDP
are _not_ universally available. They go away if you set CONFIG_INET=n.

Some folks might find it instructive to do a google code search

Even simple things like NTP will spew failures with this CONFIG_IGMP
thing turned off. And that's just the tip of the iceberg.

This option *is* disabled in the kernel for (most) Sony digital cameras.

Well, I do. To be exact, I've developed parts of it. But it's numbers
