There are a lot of people involved in openwrt, and one of the more
invisible (doesn't do irc) is juhosg.

(This might account for his productivity, I don't know!)

Among many other things, Gabor is responsible for much of the ar71xx
architecture that is in cerowrt.

This is the commit that landed today. My hat is off to Gabor...

(and darn it, I have to do a new build now)

My last known 'boot to a working internet connection' was about 126
seconds, when last I measured it.

30 seconds would be good... and while I hope that the fix above knocks a
few seconds off the boot,
doing better would take extensive profiling that I do not have time for in
this release.

I also note that I've filed some new bugs in the bugtracker regarding some
regressions in linux 3.3 that have been fixed and will be showing up in a
stabler kernel release RSN. I'm not sure if #346 addresses my long standing
issues with multicast routing and pim or not, nor if #347 accounts for a
running out of memory problem I've seen after some extreme benchmarking
while using 4 over 6  tunneling... but we'll see.

I keep hoping to find the time to figure out why QFQ hangs, but so far, no

/me goes back to making sure bug 113 is dead, dead, dead.
