Fix

[JefferyLim]

As part of my MS Thesis at Boston University, I used OS4C as the baseline NIC design for my work.

Unfortunately, it appeared as though there were a few things that did not work in this design, and so I spent a few months fixing the repository to a working state.

That being said, there are likely bugs that I have not found yet, so hopefully this is a strong baseline that people can work off from.

I am also submitting a second PR #3 that makes the number of VFs variable and will be submitting that soon once I verify a few things.

The changes made:

1. Syntax issues
2. pcie_msix.v had some issues
3. Adding awuser/aruser to the ctrl registers (so we can read the assigned MAC address)
4. Fixed axil_cqm_aruser variable in the cpl_queue_resource_translator_inst
5. Adding AU50, an AU250 targets

One on-going issue I am in the midst of verifying is the pcie_msix.v module; I believe under small packet sizes, it ends up crashing. I have a possible fix.

Closing this draft in favor of the vf_count version, since that version is more fleshed out (and allows you to set a number of VF)
