Subject: Re: v5.5-rc1 and beyond insta-kills some Comcast wifi routers

[AMD Official Use Only - Internal Distribution Only]

I tested Kalle's patch.  Laptop connects via 5GHz band by default.  Comcast router still
crashed in a hurry.  I blocked (via NM.conf) the 5GHz mac of the router, and rebooted
the laptop. Checked that the router was using 2.4 for the laptop.  Still hung the router!

What I've done temporarily is change the unlimited return value from 0 to 4000.
Somewhere around 5325 the Comcast router gets cranky/weird, and at 5350 it is
resetting the wifi stack (without resetting the entire router).

So there's no boot time flag to turn the feature off currently?
