[etherlab-users] Corrupt mailbox response in FoE

Hi,

the current stable-1.5 branch does not work for me, when using FoE commands.
I checked the FoE datagram flow with Wireshark and detected no errors.
So I looked at the source and found a fix for my problem.
Attached you will find a patch for further discussion.

Please note: all fsm->slave by slave replacements hove nothing to do 
with the problem. (This is only code beautifying)

The important fixes are the datagram by fsm->datagram replacements found 
in ec_slave_mbox_fetch() functions.

BTW what are the differences between the datagram and fsm->datagram handles?

Best regards
Ralf
