You mean the ioctl() call is your workaround?  Then your diff is
reversed...  Save the part where you don't check the return value for
the ioctl(), it is fine, but you have to #ifdef __NetBSD__ it, and leave
the horrid code it replaces in the #else part of that.

Thanks for looking at this.  Looking at qemu code is very dangerous for
the eyes, which is why I never got around adding proper support for
tap(4) in it.
