as long as the version 4 firmware blob is present in the system, will
testers have a fully fluid test- and work-flow when migrating across
from bcm43xx to b43, without any other changes to an existing Linux
installation? (i.e. no udev tweaks, no forced upgrades of components,
etc.)
Will it Just Work in bisection as well, when a tester's kernel
flip/flops between bcm43xx and b43 - like it does for the other 3000+
drivers in the kernel?
Note that we are _NOT_ interested in "might" or "can" scenarios. We are
interested in preserving the _existing_ bcm43xx installed base and how
much of a seemless migration the b43 transition will be. _THAT_ is what
the "no regressions" upstream rule is about, not the "ideal distro"
scenario you outline above. It is YOUR total obligation as a kernel
maintainer to ensure that you dont break old installations. How hard is
that to understand? This is not rocket science.
