This looks like an ommission from the default configs on the MMU
platform - thanks for pointing it out.

Auto-setting a kernel option in response to a system/vendor option is
tricky - they are independent configuration domains and attempting to
couple them gets messy quickly.  One option might be to do a post-config
validation (like a DRC), and flag any inconsistencies, but for now I'll
just make sure the defaults are sensible - there's no good reason to
disable packet socket anyway.

Any other experiences (good/bad/otherwise) to report on the MMU test
release?

Thanks again,

John
