For folks who don't know what Jason's doing: You can tunnel AoE
traffic through a routable protocol.

Jason, the aoeping tool in the aoetools package might be handy for
you.  Before an AoE device shows up in aoe-stat output, this
conversation must take place ("I" is AoE initiator, "T" is AoE
target):

  T: config query response (either answering a query or unsolicited)
  I: ATA device identify command
  T: ATA device identify response

You can understand the conversation if you have tcpdump and the AoE
protocol at your side:

You'll notice aoeping doesn't do the ATA device identify unless you
ask it to, but the aoe driver always does.
