kern/161805 - patch is on its way

[Li, Qing]

Hi, 

I believe I have identified the root cause based on the data provided by Larry Baird, but I am 
still verifying the patch against the mpd5 code. In a nutshell, the host route installed by mpd5
appears to be missing a flag resulting in the crash.

In the meantime, please try the following fix and let me know if it also work for you.
