[LEDE-DEV] lantiq: reduced throughput with SMP disabled

[James Finnie]

I have been doing a little testing of the updated ath9k 2.4 GHz
support, based on the image I built from r1251 from your staging area.

The ath9k seems to be massively improved under high throughput, it
doesn't load the CPU anywhere near as much as before.  The result of
this, plus the re-enabling of SMP, is that I can pretty much saturate
my VDSL downstream over 2.4GHz wifi (approx 70mbit/sec) and still have
around 30-40% CPU idle.  Nice work :)
