The reason you can't find the it in the spec is because it is
officially a no-no. But lots of people do no-no things and still have
working networks, thats one of the nice things about Ethernet. I too
use drops like this and 8 feet should be considered the absolute max
that will work, shorter is better. Just don't go crying to the vendor
if your network doesn't work and you've done things like this.
