Summary

Import the Linux device driver for the AMD Opteron A1100 and port it to
FreeBSD. This has been tested on the SoftIron Overdrive 3000, and seems
stable at 1G. There is further work needed to get 10G stable.

This still needs a few cleanups, but should be mostly ready for review.

Should this be done through a vendor import?

It will be two commits. I'm unsure how likely future imports from Linux will be due to the amount the drivers have diverged.

Fair enough - the most important part is that we have the original upstream source somewhere to facilitate a possible future comparison.
