opkg v0.2.x (the latest release series) doesn't really support this behaviour
very well. The caching logic just doesn't work. For example, I have a board
connected at the minute with a feed configured so I tried this:

    opkg install --download-only ncurses-terminfo
    ifdown eth0
    opkg install ncurses-terminfo

You'd hope that would pick up the package files from the cache but it doesn't.
So even if you put the files there yourself, you may no have a simple way to
install them.

An interim solution I can see is to put all the packages you want in one
directory then run 'opkg-make-index' from opkg-utils on that directory so that
it is a complete package feed. Then add that as a source in
/etc/opkg/base-feeds.conf.

The development branch of opkg which will become v0.3.x has much better cache
logic, it just needs finishing off and tidying up. I'm very busy at the minute
but it's getting there. Any help to close the remaining issues so it can be
released would be appreciated!
