If your EOE-Device works right and EOE is enabled, you should have a
regular ethernet device, created by the master.
The only problem is to tell the slave which IP-Adress it may use. DHCP
may be an option. but depends on the capabilities of the slave.
As I understand, for each slave there's a subnet in 192.168.0.0, where
the slave address determines that subnet. On the master side address 1
is used by definition while on the slave side any address between 2 and
254 may be set.
