So the problem was that I was running in VMware and the default adapter that
vmware configures for the VM is le(AMD PCnet). The le driver did not return
the negotiated connection speed when I ran ifconfig. I switched the vm
config over to a em (Intel gig) emulation and ifconfig returned the right
connection speed. altq now works great.
