[Cake] de-natting & host fairness

[Kevin Darbyshire-Bryant]

LEDE already has a patch included in the basefiles 'iproute2' package to 
make tc cake aware.  If you replace 
package/network/utils/iproute2/patches/950-add-cake-to-tc.patch (which 
is unaware of the nat options) with the attached nat option aware 
version then recompile, you should find you've a 'natted cake' capable 
version of the iproute utilities without adding extra packages, feeds etc.

I've not yet got around to adding a 'de-nat ipv6' option, so assuming 
you've built my latest version of cake, it can be configured to de-nat 
ipv4 but not ipv6.

Similarly I've not updated the LEDE stuff as I'd rather like some code 
review/testing done before it gets pushed out....and I get shouted at 
lots :-)
