New Revision: 231589
URL: http://svn.freebsd.org/changeset/base/231589
Log:
Add a sysctl to report the firmware build number.
Some older firmware versions have issues that can be worked around by
avoiding certain operations. Add a sysctl dev.aac.#.firmware_build to
make it easy for scripts or userland tools to detect the firmware
version.
