Ideally I'd like to utilize a stable port/driver. /usr/ports/devel/linux-kmod-compat was recommended to me (http://info.iet.unipi.it/~luigi/FreeBSD/linux_bsd_kld.html) , however I don't believe this to be a viable option since it was primarily developed to "wrap" drivers for usb webcams. Thanks for your suggestions, I will look into the ndisgen progress in any case. Hopefully USB support is more defined, or will be more defined in the near future.
