iproute2: tc cake qdisc add nat, docsis & ptm modes
Add cake nat de-masquerading mode: nat, nonat. Also docsis & ptm overhead related keywords: nat, nonat, ptm, docsis-downstream-ip, docsis-downstream, docsis-upstream-ip & docsis-upstream. Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>
