BTW, I have been getting reliable "Giant not owned" panics with an
ath card using -CURRENT from Aug 3rd. I'm not sure if this is likely
to have been fixed since. Just ifconfig'ing an IP address seemed
to reliably cause this, but everything appears to work fine with
debug.mpsafenet=1. Some details below (INVARIANTS but not WITNESS
enabled).
