Updating CPU microcode

[Dustin Marquess <dmarquess%gmail.com@localhost>]

My Googlefu has failed me in trying to find this answer...

Does NetBSD currently have a way to load new microcode on x86/x86-64
CPUs like the Linux microcode_ctl and the FreeBSD cpucontrol? I have a
few Supermicro Xeon-based servers where the Supermicro BIOS doesn't
appear to update the microcode at all, so I'm having to resort to
updating it at the OS level.

Thanks!
