Subject: [patch]  Gianfar : Enable promiscous mode after queue time out

	Hi all, 

	When the Netdev tx queue timeout occurred, the function
gfar_timeout(..) is called. This function calls indirectly the
gfar_init_mac(..) function.

 	In this function, the rctrl register is set to a default value.

 	If the Promiscuous is enable on the net dev ( flag IFF_PROMISC
is  set), the gfar_init_function does not reactivate it.

 	The Promiscuous mode is used for example when the netdev is
bridged.
 	
 	I apply this patch on the kernel 3.8-rc4 to fix it.

	Signed-off-by : Voncken C Acksys <cedric.voncken@...sys.fr>
