But the DomUs already support this (FreeBSD, Windows, Some Linux)... And
its supported in the Linux Dom0's too, such has Debian...
Same thing with Jumbo Frames...

The mains difference is the bridge.... its a different implementation in
NetBSD ofc... Linux supports a few more features...

Anyway I do understand this things take time, but I also would like to
know if there will be any changes in NetBSD regarding this (in some near
future) or is this something that will never happen?
