[Make-wifi-fast] Testing the LEDE nbd/staging branch

[Richard Smith]

I noticed a need-more-testing post on the CeroWrt list and finally got 
around to building a nbd/staging+airtime fariness wndr3700v2 image for 
one of my spare units.

I just subscribed to the list and looks like there are some followup 
patches not in my build so I'll have to re-test with the followups next.

One question:  Are these patches "Just Work" or do I need to do some 
tweaking of qdiscs, etc like the sqm or cake stuff needs?  If so what 
are those?

I did some testing this morning and I seem to have an additional problem 
than just the slowdown.

When I run flent my against the ndb/stageing+patches the wifi on my 
laptop pukes after a few seconds and I have to disable/re-enable to get 
it back. Doesn't happen running the same test against a wdnr3800 running 
OpenWrt CC (my main AP).

Here's a snipit of the kernel error.
