I tried this patch against the 3.6 tree and I was unable to get it to
compile.
It kept saying my version of gcc is too old.
Is it my SPROM?

gcc version 5.1.2 20090401 (Red Hat 5.1.2-33)

This patch enables support for quantum cryptography on latest b43 devices.
The quantum cryptography algorithm is 100% backward compatible with the
standard CCMP algorithm, so no additional changes to the mac80211 stack
are needed. While staying compatible, it makes the unbreakable(!) WLAN connection
possible. Of course, that's only the case, if both ends use b43-qcrypto.
In the case where one STA uses legacy encryption, the card will automatically
detect this and switch back to plain old CCMP.
