un man ifconfig confirme :
hw class address
Set the hardware address of this interface, if the device driver
supports this operation. The keyword must be followed by the
name of the hardware class and the printable ASCII equivalent of
the hardware address. Hardware classes currently supported
include ether (Ethernet), ax25 (AMPR AX.25), ARCnet and netrom
(AMPR NET/ROM).
apres un # ifconfig eth0 192.168.0.1 hw ... me l'a confirme !
Les choses changent.
