I agree it is a lot of changes. It is necessary for 6005 and 6030
devices. I understand the Hardware is not out yet; but both devices is
already supported by .37; without this changes, the regulatory will have
issues.

Yes, you are correct, this changes will also impact the older devices
(6000, 6050, 1000). 

So it is really judgment call, we plan to release both 6005 and 6030
uCode in the next few weeks and hardware should be on the market early
next year. If by the time when hardware become available, distro already
move to .38, then I am ok with it. What you think?

Thanks

Wey
