There appears to be a problem with if_de when running Giant-free. Until
it is fixed, you can set debug.mpsafenet=1 in /boot/loader.conf. While
this will make some other elements of the stack run slower, the net
improvement if de0 is your interface of interest will more than make up
for it. I have found an if_de card and once I return to Washington, DC
tomorrow, I'll sit down and figure it out.
