Hi Logan,

On 08/10/15  I pushed an 'exposeinterval' feature branch to both mine &
dave's sch_cake & tc-adv repos (so module & user side changes) which
exposed the interval (rtt) parameter.  By the following morning it even
worked!  On Morning of 11th Dave sent an email "adding 'rtt' support
correctly" to which I rather assumed my 'exposeinterval' branch was
superfluous, incorrect and unneeded so I removed them from Dave's repos
in the expectation of great things.

You'll still find my original versions of that branch
https://github.com/kdarbyshirebryant/sch_cake/tree/exposeinterval &
https://github.com/kdarbyshirebryant/tc-adv/tree/exposeinterval

A glance over Dave's patch suggests the only difference to the
'rtt/interval' side of things between his & mine is using nanoseconds in
the pass from user-space to kernel space rather than my use of milliseconds.

If you provide tc with a 'rtt 300ms' parameter it should work a treat.

Kevin
