hrm doesn't look like it has changed anything on my end.

i applied this patch against the 11.0.1 svn source:
https://svnweb.freebsd.org/base/head/sys/dev/xen/netfront/netfront.c?view=patch&r1=308126&r2=308125&pathrev=308126

then built/installed a kernel after applying this patch with no change. 
I don't think i need to rebuild world for this, right?

Cheers!
