Public bug reported:

Binary package hint: linux-source-2.6.17

The Ata-over-Ethernet kernel module doesn't discover the available
"blades" and therefore it is not possible to mount any block devices
that where exported via the "vblade" server.

Actually, nothing works the way it should: the udev file system entries
(/dev/etherd/*) are not created, and even when created manually with
"aoe-mkdevs /dev/etherd" they fail to function (try "sudo echo 1 >
/dev/etherd/discover").

A quick and easy test:

sudo apt-get install aoetools vblade

# export the device locally:
sudo vblade 1 1 lo /dev/hda &

# tell the kernel to find it:
sudo modprobe aoe
sudo aoe-mkdevs /dev/etherd
sudo aoe-discover
sudo aoe-stat

On my system, "aoe-stat" doesn't return anything.
A find | grep in /sys/ doesn't reveal anything related to "etherd" or "aoe".

If, however, I replace the module with the latest compiled from Coraid's source 
(version 40), everything works great; in the above test I get the correct 
response from aoe-stat:
"e1.1  40.027GB  lo up"
and I can mount "/dev/etherd/e1.1p1" without problems.

This problem happens with:
- aoe kernel module version 22 (linux-image-2.6.17-10-generic)
- aoetools 10
- vblade 10-1
