: ifconfig uses plain ioctl's for that, it doesn't know anything about struct 
: ifnet.  What suffers from changes like this are programs that use kmem(4) to 
: access the ifnet list directly.  A grep turns up: routed(8), ifmcstat(8) and

OK.  I was worried this might break the 'nfs mounted source/object'
upgrade path.  Sounds like it won't.  Thanks for the confirmation.
